Two dendritic nonlinear optical chromophores A-B based on the bis(3-hydroxypiperidin)aniline and bis(N-ethyl-N-hydroxyethyl)aniline donors and three 3,5-bis(benzyloxy)benzoic acid derivative isolation groups were designed and synthesized. The UV absorption, density functional theory (DFT) calculations, thermal stability, and electro-optic activity of these chromophores were systematically investigated in this article. The chromophores A-B exhibited good thermal stability at decomposition temperatures (T_d) greater than 260 °C. Most importantly, steric hindrance groups could effectively reduce dipole-dipole interactions between molecules and improve the conversion efficiency of the first-order hyperpolarizability (β) of chromophores into large electro-optic (EO) coefficients (r₃₃). A large r₃₃ value of 236 p.m./V have been achieved for chromophore B. And the poling efficiency (2.79 ± 0.08 nm²/V²) of Chromophore B at 1310 nm was much higher than that of chromophore with single donor with similar structure.

The world is filled with bright and diverse colors. In many cases, color layers need self-cleaning abilities to maintain their vibrancy and reduce cleaning costs. This study presents a new superhydrophobic self-cleaning structural color film with an anti-opal design. The system is made of fluoropolymer with an anti-opal structure that produces a striking structural color. After ultrasonic treatment, the roughness of the film increases (Ra increases from 69.8 nm to 95.5 nm, Rq increases from 95.7 nm to 120 nm), resulting in super-hydrophobicity, and the water contact Angle reaches more than 150°. When the surface's superhydrophobic layer is damaged, the film's properties can be restored using adhesive surface stripping technology. Regenerate more than 5 times. Additionally, the system shows dual thermosensitive behavior in terms of both color and hydrophobicity due to the phase changing nature of the fluoropolymers. When applied to information security, it allows for dual verification of data. The film has excellent information display effect and self-cleaning performance. It has potential application value in complex information security, display, and self-cleaning.

Acute kidney injury (AKI) leads to an increase in glomerular filtration barrier porosity and interstitial space, resulting in a rapid decline in renal function and posing a significant threat to the health of hospitalized patients. In this study, indocyanine green (ICG)-doped nanoparticles (nanoICG) were developed and, based on FDA-approval polymeric formulations and found these non-small nanoparticles with ∼300 nm exhibited a longer residence time in the kidneys of mice suffering from drug-induced kidney injury. In contrast to previous attempts to develop renal-clearable molecular probes or ultrasmall nanoparticles (1–10 nm), this work provided new inspiration for the development of a nanoscale delivery system for kidney injury treatment helping to prevent the progression of the disease.

Two donor-acceptor (D-A) type pure blue thermally activated delayed fluorescent (TADF) emitters have been synthesized by integrating two oxygen-bridged triarylborane acceptors with different phenyl rings substitution sites with 10,10-diphenyl-5,10-dihydrodibenzo[b,e][1,4]azetidine (PASi). These emitters successfully keep the rapid reverse intersystem crossing rates characteristic of D-A type TADF materials, while incorporating the short-range charge transfer (SRCT) properties of oxygen-bridged triarylborane acceptors to amplify non-radiative transition processes. Organic light-emitting diode (OLED) devices based on these pure blue emitters show that each maximum external quantum efficiency (EQE_max) of the pPhBO-PASi and mPhBO-PASi devices are 20.4 % and 15.3 %, respectively. More encouragingly, the efficiency roll-off of the device improves with the increase of doping concentration. This work provides a simple and feasible molecular design strategy to design pure blue TADF emitters.

We designed and synthesized two blue fluorescent dopants, 3,8-diisopropyl-N1, N6-diphenyl-N1,N6-bis(8-phenyldibenzo [b,d]furan-2-yl)pyrene-1,6-diamine (DBF-DIP) and N1-(dibenzo [b,d]thiophen-2-yl)-3,8-diisopropyl-N1,N6-diphenyl-N6-(8-phenyldibenzo [b,d]thiophen-2-yl)pyrene-1,6-diamine (DBT-DIP), by introducing dibenzofuran and dibenzothiophene side groups, based on pyrene core chromophore. The synthesized two compounds, DBF-DIP and DBT-DIP, exhibited decomposition temperatures (T_d) of 496 °C and 505 °C, respectively, along with glass transition temperatures (T_g) of 170 °C and 174 °C, indicating their excellent thermal stability. When used as dopants in OLED devices, both DBF-DIP and DBT-DIP exhibited an excellent electroluminescent (EL) device performances with current efficiencies (CE) of over 10 cd/A. Especially, the DBT-DIP device demonstrated a maximum external quantum efficiency of 8.25 % and CE of 11.2 cd/A at 10 mA/cm².

Herein, the design and synthesis of blue luminogens (t-BuTPAniq and t-BuTPA2niq) were reported, which employed 4-(tert-butyl)-N-(4-(tert-butyl)(5-phenyl)-N-phenylaniline (t-BuTPA) as the electron donor (D) and isoquinoline (iq) as the electron acceptor (A), linking via naphthalene π-bridges. In toluene solution, t-BuTPAniq and t-BuTPA2niq exhibited emission wavelengths (λ_max) of 462 nm and 454 nm, with photoluminescent quantum yields (PLQY) of 34 % and 38 %, respectively. Notably, t-BuTPAniq presented a PLQY of 71 % and t-BuTPA2niq showed a PLQY of 79 % in neat film, indicating that these two complexes might display aggregation-induced emission (AIE) characteristics. In dichloromethane solution, the photoluminescence lifetimes of t-BuTPAniq and t-BuTPA2niq were 61.9 ns and 67.9 ns at room temperature, respectively. Futhermore, the experiments proved that these molecules possessed distinct AIE characteristics and reversible mechanical chromic properties. Their notable acid-base color-changing capabilities were advantageous for applications in fluorescence anti-counterfeiting. Organic light-emitting devices (OLEDs) fabricated with t-BuTPAniq and t-BuTPA2niq exhibited blue electroluminescence with emission peaks at 472 nm, achieving maximum external quantum efficiencies (EQEs) of 4.0 % and 3.6 %, respectively. In summary, these molecules presented a novel research direction for developing multifunctional blue electroluminescent materials, indicating significant potential for applications in displays, lighting technologies, and fluorescence anti-counterfeiting.

The aryl phosphine oxide (APO) groups have been widely studied as host materials in organic light-emitting diodes (OLEDs). However, their application as emissive materials has been rarely explored, especially in the preparation of nondoped devices. In this work, two hybridized local and charge-transfer (HLCT) molecules, 2tBuCz-APO and 2TPA-APO, are developed by incorporating the donor groups tert-butylcarbazole (tCz) and diphenylamine (DPA) into phosphafluorene oxide unit. The experimental results demonstrate that phosphafluorene oxide derivatives exhibit HLCT characteristics, marking the first time that HLCT characteristics have been realized based on APO. As a result, the nondoped OLED based on 2tBuCz-APO exhibits the best performance with an excellent maximum external quantum efficiency (EQE_max) of 7.3 % and Commission Internationale de l’Éclairage (CIE) coordinates of (0.14, 0.15). This molecular design strategy has demonstrated that phosphine oxide, as an acceptor unit, shows promising potential for the development of highly efficient nondoped OLEDs.

This study explores, for the first time, the use of a diketopyrrolopyrrole (DPP) derivative as an optical waveguide for the fabrication of photonic circuits, where light transmission in different directions is possible depending on the excitation point. This is a key factor in the development of a new generation of miniaturized and versatile photonic chips. The DPP core was chosen for its thermal stability and exceptional optical properties, which are crucial for efficient light transmission in photonic devices, with a particular emphasis on the high fluorescence of the described derivative. Additionally, this compound exhibited a mechanofluorochromic response to mechanical stimuli. The reversible transition between different phases, along with its light-guiding capabilities, presents significant potential for practical applications, including security inks, rewritable materials, and advanced optical technologies.

Cancer stands as the second leading global cause of death, following heart disease. Considering the severe side effects revealed by some chemotherapeutics for tumor treatment and anticancer therapies, the scientific community is actively exploring more effective alternatives. Photodynamic Therapy (PDT) mediated by porphyrin-based photosensitizers (PS) has emerged as an attractive alternative to more conventional therapies. In this study, we incorporated bis-cyclometalated iridium(III) complexes featuring porphyrin-arylbipyridine ligands into poly(vinylpyrrolidone) (PVP) micelle. This integration resulted in photostable PVP-PS formulations with a remarkable capability to generate singlet oxygen. These formulations were also efficiently internalized by HT-1379 cells and due to these features, their photodynamic action against human bladder cancer cells (HT-1376 cell line) was assessed. All the formulations demonstrated high photodynamic activity, with PVP-2 and PVP-3 proving to be the most promising PS, as evidenced by their lower IC50_PDT values. It was also demonstrated that all PVP-based formulations provide a safe and effective approach for photodynamic therapy (PDT) in bladder cancer, as no cytotoxic effects were observed in Vero cells.

In this study, we report the production of biodegradable microbeads using the poly [(R)-3-hydroxybutyric acid] (PHB) polymer. To introduce functionality, we engineered Escherichia coli strains to produce biodegradable PHB by expressing indole oxidase, enabling the synthesis of biodegradable polymers containing either indigo or indirubin. The formation of indigo or indirubin or both is dictated by the symmetrical or asymmetrical dimerization of oxidized indole products, which depends on the specific oxidation position. To increase the content of indirubin—a compound with known anticancer properties—relative to indigo (commonly used as a dye for denim), isatin was supplied during synthesis. This approach yielded indirubin-PHB biodegradable films with enhanced indirubin content. Furthermore, during the film fabrication process, photodegradation of indigo was induced, further enriching the relative indirubin content ratio. Using these indirubin-PHB films, biodegradable microbeads with diameters below 200 μm was successfully produced. Characterization of these microbeads confirmed the incorporation of indirubin, resulting in functional biodegradable microbeads. Finally, a prototype facial cleanser containing indirubin-PHB microbeads was developed, suggesting the potential of these eco-friendly microbeads as cosmetic ingredients for future applications.
