摘要:
Disclosed herein is novel highly stable, crystalline porphyrin containing covalent organic frameworks and their synthesis using Schiff base reaction which are hydrophobic in nature having good selectivity towards alcohol uptake at low pressure over water. Particularly, present invention provides novel highly stable, porous covalent organic frameworks (COFs) comprising porphyrin linked hydroxyl aromatic compound by intramolecular O—H—N═C bonding; wherein porphyrin is tetra(p-amino-phenyl)porphyrin (Tph) and hydroxyl aromatic compound is selected from group consisting of Triformylphloroglucinol (Tp), 2, 5-dihydroxyterephthalaldehyde (Da).
摘要:
The present invention is directed to a process for the preparation of phosphoric acid loaded covalent organic framework (PA@Tp-Azo and PA@Tp-Stb) with high stability and high proton conductivity.
摘要:
The present invention disclose photochromic metal organic frameworks (MOFs) containing photochromic 1,4,5,8-naphthalenediimide (NDI) core and metal ions selected from Mg, Ca or Sr. The developed MOFs find application in inkless and erasable printing wherein they retain the photogenerated colour for a prolonged period of time so that the printed content remains legible/readable for reasonable time.
