ABSTRACT We point-out an exceptional tailorability of iron(III) trimesate metal-organic framework to bio-friendly conditions. This is particularly attractive in sight of one-pot immobilization of biomolecules for biomedical applications. Synthesis is carried out via mechanochemical approach under green, biocompatible conditions without additional solvents, in just 1 hour, at room temperature. Solvents are proven to be unnecessary to build the framework, in contrast to solution-based methods. Microstructure and thermal stability of the material are not affected by pH. Conversely, textural properties can be tuned by simply varying the amount of base. Graphical abstracrt

ABSTRACT Since the serendipitous discovery of cisplatin, thousands of inorganic molecules have been synthesized in search of new drugs endowed with powerful anticancer activity and safe profile. As matter of fact, this “magic” and desired combination to date remains unmet. On the other side, after cisplatin, only two additional platinum-based drugs -that have been substantially designed as cisplatin-like molecules- have been approved at the global level, i.e., carboplatin and oxaliplatin. Accordingly, here, we try to summarize and highlight some relevant reasons for this “lack” of newly approved molecules. Also, we try to rationalize what are the critical steps in the discovery process (and approval) of new ameliorated anticancer metallodrugs, contributing to stimulate an open and critical scientific debate.

ABSTRACT In the present study, detailed investigation on postdeposition halides treatment using CdCl2, CdI2, MgF2, MgCl2 and MgI2 is undertaken over thermally evaporated CdTe films. As-deposited films are subjected to halide treatment and subsequent annealing at 385°C. Halide activation induced grain growth mechanism is presented along with anions and cations roles on change in films properties and formation of different complexes. XRD patterns of all CdTe thin films exhibited polycrystalline nature with preferential cubic phased (310) plane except for CdI2 treated films where preferred reflection is appeared corresponding to (220) plane. Grain growth is observed with treatment employing amicable estimation tools. All films have a conspicuous ohmic character owing to linear I–V plots. Optical study reveals that CdCl2 treated CdTe films have higher absorbance and optical energy band-gap is measured out in the range 1.42–1.53 eV with halide treatment. Surface topography and PL study revealed to variations in surface roughness and photoluminescence peaks intensity with halide treatments. Film growth and treatment are validated by EDS analysis and FESEM images demonstrated explicit grain growth. Findings warrant amazing role of halide activation on film properties and CdCl2 is found a suitable surface treatment agent to CdTe films in order to develop better devices. Graphical abstract

ABSTRACT Pillar-layered metal-organic frameworks (PL-MOFs) are advanced crystalline porous substances built using metal ions, oxygen- and nitrogen-donor linkers. The pillar-layered strategy emerged as a very effective way to incorporate the Schiff base functionalities into pore cages of MOFs by using N-donor Schiff base pillar ligands. The Schiff base functionalities provide active sites for enhanced performance in sensing, catalysis, adsorption, extraction, and gas separation areas. Although the PL-MOFs have gained remarkable advances in the last few decades, Schiff base PL-MOFs have been reviewed to a lesser extent up to this point. In this way, a review summing up their performance is profoundly expected. This review covered the recent developments connected with Schiff base PL-MOFs, including synthesis and applicability in various potential fields. It also included the challenges and forthcoming pathways for fulfilling the research and development needs of Schiff base PL-MOFs. ABSTRACT

ABSTRACT Piperazine, a six-membered nitrogen-based heterocycle, is widely distributed in nature and also has great therapeutic efficacy due to abundant of large number of biomolecules with multiple functions. Owing to the activities, developments of piperazine-based compounds are receiving great attention among the research chemists. Nowadays, piperazine and its various homologues exhibit various biological roles such as antibiotics, anticancer, antimicrobial, antipsychotics and antidepressants. In this context, various piperazine-based metal-Schiff base complexes have been synthesized to investigate their catalytic and biological activity. In addition, a large number of Schiff base transition metal compounds have been reported which play a significant role in biology due to their potential antimicrobial, antifungal, antitumor, antiviral and antidiabetic properties. The present review encompasses the applications of various aminoethylpiperazine-based metal Schiff base complexes. Aminoethylpiperazine is one of important structural motifs which have different active sites/structural features and capable to bind with the metal ion to form chelate ring and also explore biological and catalytic properties of its Schiff base-based metal organic complexes. This review mainly focused on the catalytic and biological importance of aminoethylpiperazine-based metal organic complexes during the period of 2012–2020.

ABSTRACT Zeolite membranes are widely used in separation, catalysis, sensors and other fields because of their good diffusion performance, shape selection and catalysis capabilities. However, the slow synthesis rate of zeolite membranes restricts their industrialization process, and the random orientation seriously affects their performance. Therefore, this paper investigates the methods for accelerating the synthesis rate of zeolites and the roles of different methods was explored. The synthesis conditions of oriented zeolite membranes are also summarized. Microwave method can efficiently synthesize oriented zeolite membranes, but it has the defects of harsh synthesis conditions and high equipment requirements. Using physical methods and chemical methods to introduce hydroxyl radicals, which is also an effective method to improve the synthesis rate of zeolites. However, there is a lack of research on how to realize the directional synthesis of zeolite membranes during this process. Synthesis conditions, template and support properties affect the directional synthesis of zeolite membranes. Therefore, while introducing free radicals, adjusting the composition of the synthetic solution or introducing inhibitors that affect the growth direction of zeolite in the synthetic system can realize the efficient directional synthesis of zeolite membrane, which is another potential method to promote the industrialization of directional zeolite membrane besides microwave method.

ABSTRACT As a product of photosynthesis, the storable chemical energy in the form of carbohydrates inspires the people engaged in renewable energy research to mimic the natural process. This may be the reduction of the proton or carbon dioxide to produced fuels e.g., hydrogen or CH4 and CH3OH or other chemical feed stocks e.g., HCOOH, CO32-. (COOH)2. This replication of the natural process is known as Artificial Photosynthesis. In either case water oxidation is mandatory. Herein, we discuss brief mechanism of photosynthesis, emphasizing the role of Water Oxidation Catalyst (WOC). Literature on Manganese based WOC is presented with their characteristic features.

ABSTRACT This review analyses and discusses the methods, medium, matrix, and mechanisms of α-cyclodextrin (α-CD) based sensors reported in the literature. Small guest molecules are detected directly by the α-CD host molecule by capturing them in the cavity through host-guest complexation. Whereas big size species are detected by the probes tagged on the 1°/2° rim of the α-CD. i.e., on the exterior of the cavity. This is the first review report on the α-CD-based sensors.

ABSTRACT Metal Organic Frameworks (MOFs), built from metal ions/clusters coordinated by organic linkers/bridging ligands, have emerged as an extensive class of crystalline hybrid materials with exceptional ultrahigh porosity and enormous internal surface areas. Out of several hallmarks possessed by MOFs, one is their topologically diverse and aesthetically pleasing framework structures which can be adjusted and tuned with the state-of-art techniques, and molecular simulations, different geometry, and connectivity of a linker to the respective metal cluster. In this critical review, we intend to highlight the scope of carboxylate-based MOFs by providing a varied range from their topology analysis and molecular simulations to different synthetic routes. Moreover, providing insights to reticular chemistry of carboxylate MOFs and the importance of Post-Synthetic Modification (PSM), an alternative route to introduce functional groups within these MOFs. We have also tried to identify the possible loopholes that can provide an extensive opportunity to young researchers that can lead to a detailed exploration in the field of novel MOFs.

ABSTRACT A new recyclable and stable catalyst based on a Zr metal-organic framework, namely MIP-202 has been constructed through a simple post‐synthetic modification strategy as an extremely efficient and applied heterogeneous catalyst for Knoevenagel condensation reaction between benzaldehyde and ethyl cyanoacetate under mild reaction conditions. The principal purpose of this study is to reduce the amount of the protonated amine functional groups (NH3 +) in the pores of MIP-202 using the solvent assisted ligand exchange (SALE), in order to achieve an optimal structure to obtain higher efficiencies in Knoevenagel condensation reaction. The resultant catalyst is characterized via various techniques including PXRD, FT-IR, FE-SEM, EDX, BET, AAS, CHN, and TG analyses. The post-modified catalyst exhibited high catalytic performance with 90% efficiency, which is an enhanced activity compared to the pristine MIP-202 MOF, and also four recycling stability without a significant decrease in catalytic activity. Therefore, it was proved that the adjustment of functional groups is an effective method for the improvement of the reaction process. The catalytic mechanism has also been investigated.
摘要:通过简单的合成后改性策略，构建了一种新型的可回收、稳定的Zr金属-有机骨架催化剂MIP-202，作为在温和反应条件下苯甲醛与氰乙酸乙酯之间的Knoevenagel缩合反应的高效非均相催化剂。本研究的主要目的是利用溶剂辅助配体交换(SALE)减少MIP-202孔隙中质子化胺官能团(NH3 +)的数量，以获得最佳结构，从而在Knoevenagel缩合反应中获得更高的效率。所得催化剂通过PXRD, FT-IR, FE-SEM, EDX, BET, AAS, CHN和TG等多种技术进行了表征。改性后的MIP-202 MOF具有较高的催化效率(90%)，与原始MIP-202 MOF相比，活性有所提高，并且具有4个循环稳定性，且催化活性没有明显下降。由此证明，官能团的调整是改善反应过程的有效方法。并对催化机理进行了研究。
