The synthesis, photophysical and photoacoustic characterization for a series of nine π-extended quadrupolar curcumin dyes is presented. A systematic evaluation of the π-bridging unit including the p-phenyl, naphth-4-yl, thien-2-yl and hybrid 4-naphthathien-2-yl groups is presented. Furthermore, evaluation of the strongly

A series of push-pull heterocyclic N,N-diphenylhydrazones were prepared to study the effect of structural modifications (different π-spacers and electron-withdrawing groups) on the optical (linear and nonlinear) and electronic properties of the molecules. The photovoltaic response of dye-sensitized solar cells assembled
