Supramolecular cages and metal organic frameworks of porphyrins for a sustainable tomorrow: challenges and applications

Abstract

Engineering of porphyrin based imine linked supramolecular cages and MOFs for electrocatalysis and photocatalysis is summarized. Their broad applications for artificial photosynthesis and energy conversion were discussed.

Porphyrin-based metal–organic frameworks for photo(electro)catalytic CO2 reduction

“…These cages are typically constructed from numerous organic molecules through non-covalent interactions, such as hydrogen bonding and hydrophobic effects, resulting in an organic molecular system with a hollow interior. 53,90,91 Hollow self-assembled molecular cages possess remarkable capability to selectively include chemicals within their established cages. Additionally, they can aid in guest stabilization, storage, and transportation, as well as catalyze guest transformation in a controlled manner.…”

“…Kitagawa and collaborators were the first to propose the concept of pillars in MOFs. 90 In this structure, the layers are bonded to each other through hydrogen bonds, resulting in a 3D arrangement. 93,94 The design and modification of 3D porous materials are significant breakthroughs owing to the widespread application of the materials for guest molecule adsorption.…”
