A photochromic Cd(ii)-organic framework showing highly efficient dual-response sensing properties

Abstract

A photochromic Cd(ii)-organic framework shows highly efficient dual-response sensing behavior towards TNP and MnO4−.

A photochromic metal–organic framework with a rare 3D self-interpenetrated architecture and an ultrahigh MnO4− sensing ability

“…Previously, L was used by our group to construct two MOFs, {[Cd 1.5 (L)(HOBA)(EtOH)(SO 4 )(H 2 O)]·3H 2 O} n ( a ) 38 and [Cd 2 L (HBTC) 2 ·2H 2 O·2i-PrOH] n ( b ). 39 They show a 1D triple chain and a 2D (4,6)-connected network, respectively. However, 1 features a more complicated 3D self-interpenetrated (4,4)-connected structure.…”

“…Recently, our group developed new diarylethene-type photochromic organic ligands to construct LMOF-based sensing materials. 38–40 For example, {[Cd 1.5 ( L )(HOBA)(EtOH)(SO 4 )(H 2 O)]·3H 2 O} n ( a ) 38 and [Cd 2 L (HBTC) 2 ·2H 2 O·2i-PrOH] n ( b ) 39 are fabricated using a new dihydroanthracene-based photochromic ligand L . a has a 1D triple-chain architecture and can sense MnO 4 − with extremely high sensitivity and good selectivity after photochromism.…”
