Humidity-Triggered Reversible 0-1D Phase Transition in Hybrid Antimony Halides.

ABSTRACT: Stimulus-responsive inorganic-organic hybrid metal halides (IOMHs) have shown great potential in applications such as sensing and anti-counterfeiting. IOMHs can undergo a variety of structural changes when triggered by humidity; however, relevant reports of structural dimensionality change from zero dimension (0D) to one dimension (1D) are rare. This study investigates the synthesis, structure, and properties of two antimony-based IOMHs, namely 0D-(Mp)₃SbCl₆·MeCN and 1D-(Mp)₂SbCl₅ (Mp = protonated morpholine; MeCN = acetonitrile). Photophysical characterizations show that (Mp)₃SbCl₆·MeCN, when being excited at 375 nm, exhibits typical self-trapped exciton triplet state broad-band emission, with a peak at 620 nm and a quantum
