Abstract A viologen‐based Borromean entangled porous framework was found to be sensitive both Cu Kα and Mo X‐ray sources, showing rapid photochromic response recovery within one minute. The X‐ray‐induced process is accompanied by a reversible single‐crystal‐to‐single‐crystal (SC‐SC) structural transformation, an unprecedented phenomenon for materials. complex can further processed into portable thin films detecting the dose of exposure. Moreover, photochromism occur over broad temperature...

Hydrogen-bonded organic frameworks (HOFs) have been well recognized for constructing solid-state proton-conducting materials due to their inherent well-defined H-bonded networks; however, the design and synthesis of stable HOFs showing ultrahigh superprotonic conductivity is still challenging. Herein, we reported a facile effective synthetic strategy build high metalo hydrogen-bonded organic–inorganic (MHOFs) through charge-assisted inorganic synthons. The supramolecular self-assembly simple...

Interests in chromic materials are rapidly increasing for their potential applications as smart responsive materials. However, the majority of existing ones triggered by merely one or two outer stimuli and few multi-stimuli examples still suffer from confining functioning state such solution polymer. To address these challenges, a new generation is being intensively pursued. In this article, we report neoteric supramolecular solid material assembling Co(II) ion with...

Although naphthalene diimide (NDI) and its derivatives have been widely used for organic Li-ion batteries (OLIBs), they are limited by a low lithium uptake capacity ambiguous lithiation mechanism. Herein, we report two isometric thionated-NDI cathodes (cis-2S trans-2S) obtained replacing O with S in the imide groups which improves battery performance compared parent NDI (P-NDI). Remarkably, position of atoms plays an important role as potential plateau cis-2S was 100 mV higher than trans-2S,...
