Two donor–acceptor metal-free organic dyes, CR29 and CR52, featuring two isomeric benzodithiophene (BDT1 or BDT) π-spacers have been synthesized. The dyes display good extinction coefficients in the visible spectral region 400–650 nm and promising performance in DSSC. Theoretical and experimental investigations established that in such architectures, the BDT1-based dye outperformed the BDT-based dye.
