Organic room temperature phosphorescent (RTP) materials have emerged as a prominent research area due to their unique luminescent properties and wide applications. However, it remains a great challenge to realize a distinct RTP modulation by one stimulus, although it is highly desirable for developing high-level information encryption. Herein, we fabricate two distinct RTP films by incorporating terpyridine (Tpy) derivatives with a carboxylic or amine group into polyvinyl alcohol (PVA), exhibiting entirely different optical responses upon the introduction of dynamic lanthanide (Ln) coordination. The RTP film fabricated by carboxylic group-functionalized Tpy derivative shows significant changes in fluorescence and RTP emissions upon the addition of Ln3+ due to efficient triplet-to-singlet Förster resonance energy transfer (TS-FRET). On the contrary, the RTP film prepared by amine group-functionalized Tpy derivative demonstrates almost unchanged optical properties after introducing Ln3+. Encouraged by such a distinct Ln3+ modulation, multi-level information encryption is well demonstrated with a largely improved security level. This study not only contributes to the development of modulable RTP materials but also promotes the advancement of high-level information encryption.

An anisometric Eu(III) complex was used to produce nanoscale and microscale films by three different methods. These films demonstrated considerable differences in their supramolecular organization and optical properties. The impact of the fabrication method and supramolecular organization on optical properties of the films was studied. The nanoscale films deposited from solutions were found to have excitation spectra identical to those of diluted solutions with the maximum at 330 nm. The microscale films fabricated by vitrification from their melts or solvent evaporation from solutions were found to contain J-aggregates. Their spectra were comparable to those of concentrated solutions with the maximums at about 400 nm. For the first time, we report growing a monocrystal of a lanthanide’s mesogenic complex and its characterization by X-ray crystallography. The type of intermolecular interactions was identified and the size and shape of the aggregates were characterized. Formation of J-aggregates in microscale vitrified films was shown to be the key factor that provided these materials with the properties of excitation not only by UV light but also by inexpensive visible light sources with wavelengths corresponding to the absorption range of 390–425 nm.

The formation features and spectral properties of Langmuir floating layers of 5-(4-hydroxyphenyl)-10,15,20-tris(4-hexadecyloxyphenyl) porphyrin on an aqueous subphase with different content of orthophosphoric acid (H3PO4) have been studied. The acid concentrations were 0, 10–3, 10–2, 10–1, 1 M, which corresponded to subphase pH values of 5.3, 3.1, 2.3, 1.6, 1.1, respectively. At low acid concentrations (CH3PO4 = 0 M and 10–3 M), only one condensed phase with edge-on orientation of porphyrin molecules as formed. At high concentrations (CH3PO4 = 10–1 M and 1 M), two phases with face-on and edge-on molecular orientations were detected. The protonation of porphyrin at high acid concentrations (CH3PO4 = 10–1, 1 М) proceeds more efficiently, which is confirmed by high-intensity absorption peaks in the range of 683–700 nm and the presence of the shoulder of Soret band at 465 nm. The protonation leads to a stronger interaction of porphyrin macrocycle with the subphase, maintaining the face-on orientation not only in the gas phase, but also partially in the condensed phase. Spectral characteristics of thin films transferred onto solid substrates by the Langmuir-Schaefer method retain the features inherent to the previous floating layers. The signs of porphyrin protonation decrease at strong compression of floating layers, when they are in the condensed phase, or when LS-films undergo heat treatment at a temperature of 110 °C. Obtaining the protonated forms of porphyrins as an electron acceptor is a step towards the creation of donor-acceptor systems, effective in the development of photovoltaic devices based on organic macroheterocyclic compounds.

Peptides and proteins can co-assemble into various nanostructures based on complementary non-covalent interactions such as electrostatic forces, hydrogen bonding, and hydrophobic associations. These co-assemblies create a design space of functional materials for a wide spectrum of energy, environmental, and biomedical applications. This review focuses on the fundamentals and applications of three co-assembling systems: ultra-short peptides, peptides, and proteins. We will present and discuss experimental studies demonstrating applications in drug delivery, tissue engineering, and biomaterials development. We will also discuss the contribution of computational research, including molecular dynamics simulations and machine learning, to enhance our understanding of assembly mechanisms. Integrating experimental and computational methods would provide crucial insights for understanding and designing robust functional co-assemblies with precisely controlled compositions and properties. These advances would support the development of sophisticated biomaterials for applications ranging from targeted therapeutics to regenerative medicine.

High-affinity molecular recognition plays a crucial role in both biological and artificial host-guest systems, ensuring robustness in complex environments or at extremely low concentrations. Achieving exceptionally high binding affinity in artificial receptors remains a fundamental challenge for supramolecular chemistry. However, while ultrahigh binding affinity is desirable for stability, it may limit the dynamic behavior of host-guest systems, thereby restricting potential applications. Hence, controllable ultrahigh-affinity molecular recognition (CUAMR) systems allow guest release in response to precise stimuli (such as photo, pH and redox), which hold significant promise across diverse fields. This paper focuses on the introduction of CUAMR and functional applications of such controllable systems, highlighting current challenges and future prospects.

Self-assembly in life that creates complex creatures with colorful biological activities, relies heavily on all-scale diverse components and high-capacity assembly information, which directs assembly patterns by specifying the connectivity of components. Despite of nanoscale colloids or connectivity via DNA hybridization providing rich possibility to store information, the execution of encoding at the level of macroscopic bulk materials remains improving, especially on the connectivity diversity. Here, we demonstrate visible self-assembly of millimeter-scaled hydrogels with flexible Lego-like connectivity for high-capacity encoding by storing the assembly information of both orthogonally stimulus-responsive components and interfacial supramolecular binding. Three categories of hydrogels with response to temperature, redox conditions, and UV light, are used as the intelligent building components. Meanwhile, reversible electrostatic interactions are applied as the interfacial supramolecular connectivity, which undergoes on-demand assembly/disassembly to create diverse structures similar to Lego playing. Mechanistic study is obtained by quantify the connectivity via in-situ measurements of interfacial binding forces between components. The flexible supramolecular connectivity of responsive components has provided abundant assembly possibility with good control, leading to a high encoding capacity of over 800 billion codes for a simple 5 × 5 assembly. This strategy induces myriad self-assembly pathways to broaden the design of information storage, and improves the execution of encoding at a bulk material level.

Oleic and stearic acids were used to stabilize colloid nanoparticles and disperse them in organic solvents. Hybrid films of polymethyl methacrylate with various mass ratios of doped quantum dots and europium complexes were produced by spin-coating. The application potential of these materials as ratiometric temperature sensors was analyzed. The produced films demonstrated the highest sensitivity of photoluminescence in the temperature range of 298 – 393 K among other known analogues.

Lithium-metal batteries (LMBs) usually are regarded as the pinnacle of next-generation energy storage due to the high specific capacity and low redox potential of the Li-metal anode. However, their development is hindered by safety hazards related to flammable electrolytes and uncontrolled side reactions within the battery. Both polymer and solid-state inorganic electrolytes, despite their potential, exhibit shortcomings that limit their practical applications. Active filler-containing polymer electrolytes (AFPEs) offer a promising solution by combining the benefits of both types. Enhanced by supramolecular interactions between the polymer matrix and active fillers, AFPEs demonstrate superior electrochemical performance over traditional polymer electrolytes. This review discusses the progress in active fillers and various polymer matrices, examining the factors that enhance performance, particularly ionic conductivity. It also outlines the future research directions of AFPEs, aiming to broaden the application of solid electrolytes in high-performance LMBs.
