A carborane-triggered metastable charge transfer state leading to spontaneous recovery of mechanochromic luminescence

Chem Commun (Camb). 2016 Oct 13;52(84):12494-12497. doi: 10.1039/c6cc07093k.

Abstract

An efficient strategy was designed to realize spontaneous recovery of mechanochromic luminescence by carborane-functionalized anthracene derivatives. A metastable charge-transfer emission from anthracene to o-carborane is responsible for this process.
