Star-shaped donor-acceptor molecules are full of promise for organic photovoltaics and electronics. However, the effect branching core on physicochemical properties, charge transport photovoltaic performance such materials in single-component (SC) bulk heterojunction (BHJ) solar cells has not been thoroughly addressed. This work shows comprehensive investigation six star-shaped with terminal he...

Conjugated semiconducting polymers are key active materials for printable electronics, sensors and biosensors, organic photovoltaics, light emitting devices, more. The research in the field developed very efficient sound structure property relationships, thus making a case transition from laboratory to industrial environment. At this critical juncture, sustainability, ease of scaling up at leas...

Helicenes combine two central themes in chemistry: extended π-conjugation and chirality. Hetero-atom doping preserves both characteristics allows modulation of the electronic structure a helicene. Herein, we report (BO)2-doped tetrathia[7]helicene 1, which was prepared from 2-methoxy-3,3′-bithiophene four steps. 1 is formally derived by substituting (Mes)B−O moieties place (H)C=C(H) fragments b...
