Synthetic azobenzene-containing metal–organic framework ion channels toward efficient light-gated ion transport at the subnanoscale

Abstract

Artificial nanochannels with diverse responsive properties have been widely developed to replicate the smart gating functionalities of biological ion channels. However, in these traditional nanochannels, common responsive molecules are usually...

Light‐Controlled Ionic/Molecular Transport through Solid‐State Nanopores and Nanochannels

“…This study essentially provides a new opportunity to create smart photo-switchable system for more applications. [118]…”

“…Then, they assembled the light‐responsive proton conductive membrane with an LED lamp and realized remote‐control of the optical device. This study essentially provides a new opportunity to create smart photo‐switchable system for more applications [118] …”

Conjugated microporous polymer membranes for light-gated ion transport

“…On the other hand, light-responsive molecules must be precisely incorporated into these channels to act as the photo switches. Although several attempts have been made to fabricate membranes with light-gated ion channels (20)(21)(22), it is still difficult to control the channel structure on molecular level using the existing fabrication techniques. Only with precise design of the channel architecture and chemistry could the membranes achieve the expected light-gated ion transport and sieving.…”

A new boron cluster anion pillared metal organic framework with ligand inclusion and its selective acetylene capture properties

“…The design of advanced porous materials is vital for many applications such as gas separation 5 and catalysis. 6 Recent years have witnessed families of porous metal organic frameworks (MOFs) with excellent properties for physisorption separations. 7–16 In this context, inorganic anion pillared MOFs as a unique subclass with strong Lewis basic functional anion sites, developed firstly by the Zaworotko group 17 and Kitagawa group, 18 have been of particular interest for selective gas separation due to their high molecular recognition competence.…”

“…This ligand inclusion reduces the porosity of BSF-10 but enhances the stability for practical applications, which has never been reported in BSFs. 6 The available narrow pores without inclusion of ligands are suited for the accommodation of C 2 H 2 by cooperative dihydrogen bonding. Thus, the high capacity of C 2 H 2 (65.0 cm 3 g −1 ) as well as good separation selectivity for C 2 H 2 /CO 2 (13.52–5.86) and C 2 H 2 /C 2 H 4 (4.09–2.93) under ambient conditions are achieved.…”
