Abstract

Thermally driven reversible emission switching between different colors and solid-phase transformation are investigated for two aromatic-amine compounds bearing trifluoromethyl (CF3) groups. The phase-dependent emission properties are attributed to the different molecular packing properties and changeable molecular geometry for different solid phases (see figure).
