A dirhodanine-substituted benzothiadiazole compound has been synthesised using Knoevenagel condensation of a dialdehyde-substituted benzothiadiazole and rhodanine. The resulting compound was deep orange red in colour and shows a HOMO and LUMO levels of -5.61 and -3.85 eV respectively, which makes it suitable for applications such as acceptor for organic solar cells.
