(TK4, TK5 and TK6), composed of diarylamine donor groups, a dibenzofulvene-thiophene core as the π-bridge, and a cyanoacrylic acid anchoring group as the acceptor, have been successfully designed, synthesized, and characterized both experimentally and computationally. The performance in DSSC solar cells has been also studied. Octyloxy chains were introduced on the backbone of the dye, in order to increase
