Reversible Mechanofluorochromic Luminescence of Molecular Assembly of o-Carborane |
| 초록 |
A new type of solid-state photochromism was observed in an AB2 type molecular assembly comprising the central silole and two peripheral o-carborane units, and depending on the assembling positions of those units at adjoining phenyl group two different conformational isomers were formed, namely Si-m-Cb and Si-p-Cb. Each isomer showed different solid-state photochromism depending on its solid state morphology, either in the crystalline or amorphous state. Photophysical studies on each isomer in the solid-state revealed that electronic interaction between silole and o-carborane units determined emission colors. The crystal and DFT optimized structures each accounting for the crystalline and amorphous structure, respectively, and correlated well to the electronic interaction on the molecular assembly in the solid state, thus enabling to predict solid state morphological change, vide infra. |
