Conjugated and processable self-standing vinylene-linked covalent organic framework membranes (COFMs) are highly demanding for photonics optoelectronics. In this work, we have fabricated the first cyclotriphosphazene (CTP) cored COFM (CTP-PDAN). For comparison purposes, successfully imine-linked congener (CTP-PDA). Leveraging inherent nonlinear optical (NLO) response of CTP core, both were directly mounted to evaluate NLO parameters using open-aperture (OA) Z-scan technique. Direct...
Processable covalent organic framework membranes (COFM) are emerging as potential semiconducting materials for device applications. Nevertheless, the fabrication of crystalline and free-standing 3D COFMs is challenging. In this work, a unique time solvent-efficient triple-layer-dual interfacial (TLDI) approach simultaneous synthesis two from single system developed. Besides, first time, optical conductivity these analyzed using terahertz (THz) spectroscopy in transmission mode....
Hydrogen (H2), the next-generation green fuel, can be obtained by catalytic splitting of water using solar and electrochemical methods a combination both (photoelectrochemical). Among various porous reduction systems developed, covalent organic frameworks (COFs) based are emerging in recent times due to their structural ordering facile tunability, high thermo-chemical stability, permanent porosity. This review provides detailed summary analysis COF-based photo-, electro-,...
Abstract The vastness of organic synthetic strategies and knowledge reticular chemistry have made covalent frameworks (COFs) one the most chemically structurally diverse class materials with potential applications ranging from gas storage, molecular separation, catalysis to energy storage magnetism. Recently, this porous has garnered increasing interest as nonlinear optical (NLO) materials. Traditionally, inorganic crystals, small‐molecule chromophores, oligomers been studied for their NLO...
Metal nanoparticles (MNPs) in heterogeneous form have shown impressive potential for a range of applications optoelectronics, catalysis, and sensing. Various strategies with varying degrees success been adopted over the years heterogenization MNPs, including anchoring and/or encapsulation MNPs polymers, zeolites, silica, etc. However, these suffer from unavoidable drawbacks, such as leaching agglomeration-induced deactivation. In this work, we developed new approach to heterogenize networks...
The emerging role of Ribonucleic acids (RNAs) as therapeutics is alluring. However, RNAs are extremely labile under ambient conditions and typically need to be stored in cryogenic (-20 °C -80 °C). Hence, storage, stabilization, transportation RNA have been an arduous task remain unsolved problem. In this work, a guanidinium-based ionic covalent organic framework (COF), TTG
A superoleophilic free-standing three-dimensional covalent organic framework membrane (TAM-DNDC 3D-COFM) with hydroxyl functionalized naphthalene is fabricated interfacially. The enhanced oil-wettability and anti-fouling properties of the 3D-COFM exhibited gravity-based efficient demulsification flux at a four-order magnitude compared to phenyl cored-congener. continuous efficiency (76 400 L m
