Abstract

Abstract : An electron-deficient MOF based on the NDI derivative has been developed for selective oxidative C–C coupling of 2, 6-di- tert -butylphenol to different products by controlling the reaction conditions. Abstract : Naphthalene diimides (NDIs), a type of electron-deficient dye molecule with high quadrupole moment and excellent redox activity, have been utilized in various fields, such as energy transfer, chemical sensing, anion transport, and photo-/electrochromic materials. In this study, an electron-deficient metal–organic framework with one-dimensional channels, Eu2 (BBNDI)3 (DMF)2 (MOF 1 ) (H2 BBNDI = N, N ′-bis(3-benzoic acid)naphthalene diimide), was successfully constructed based on the naphthalene diimide derivative. Because of the generation of NDI radicals by electron transfer between components, this material exhibits fast-responsive reversible photochromic properties. Moreover, it shows high efficiency and selective oxidation of 2, 6-di- tert -butylphenol to its quinone derivative, aldehyde, and dimeric or trimeric phenol derivative by controlling the reaction conditions.
