| Abstract: | A set of benzothiadiazoles (BTD) of the type D-π-A-π-D and D1-π-A-π-D2 were designed and synthesized by the Pd-catalyzed Sonogashira cross-coupling reaction. Their photophysical and electrochemical properties were studied. The substitution of anthracene on BTD improves its thermal stability, and lowers the HOMO-LUMO gap, which results in a red shift of the electronic absorption. The experimental optical gap values show good agreement with the calculated HOMO-LUMO gap. © The Royal Society of Chemistry 2015. |
