Abstract

Abstract Designing π-conjugated molecules for mechanochromism has attracted much attention. Here, we found an approach toward mechanofluorochromic dyes, which are composed of dimeric 9-(4-methoxyphenyl)acrylonitrile-appended anthracene units bridged by an alkyl chain. The molecule in an amorphous state showed a dramatic bathochromic shift (ΔλPL = 75 nm) after grinding while a crystalline state of the monomer motif showed a small hypsochromic shift (ΔλPL = 2–20 nm).
