Solid-state temperature-dependent luminescence of <i>C</i>,<i>C</i>'-diaryl-<i>o</i>-carboranes based on restriction of excited-state structural relaxation.

ABSTRACT: Here, we show mechanistic analyses of solid-state temperature-dependent luminescence of C,C'-diaryl-o-carborane derivatives. Solid-state stimuli-responsiveness is a promising property to visualize environmental changes on the molecular scale. Thus, mechanistic study of responsiveness is meaningful for broadening the scope of materials. We previously reported solid-state temperature-dependent luminochromism of C-anthryl-o-carborane derivatives. Among them, we re-focused on C-anthryl-C'-phenyl-o-carborane as a prototypical compound and synthesized derivatives with electronically different substituents on aryl units. Based on extensive analyses with crystallography, variable temperature optical measurements and theoretical calculation, w
