Organic semiconductors with variable charge carrier polarity are required for optoelectronic applications. Herein, we report the synthesis of three novel diketopyrrolopyrrole (DPP)-based D–A molecules having three different ...

Mechanochromism is a stress induced perturbation of electronic property in molecular materials. It is shown here that the presence of a branched chiral chain facilitates mechanochromic response in a molecular assembly as ...
