Tunable mechanochromic luminescence of 2-alkyl-4-(pyren-1-yl)thiophenes: controlling the self-recovering properties and the range of chromism?
Chemical Communications Pub Date: 2019-09-12 DOI: 10.1039/C9CC06406K
Abstract
Controlling the behavior of mechanochromic luminescence (MCL) based on rational design principles is an outstanding challenge. Herein, an unprecedented self-recovering MCL that manifests in a large shift of the emission maximum (～200 nm) has been achieved for 2-alkyl-4-(pyren-1-yl)thiophenes upon introducing long alkyl chains and mixing with N,N′-dimethylquinacridone.
