The covalent linkage of phenanthrene units at 9 and 10 positions resulted in a broadening of the absorption band and a red-shift of the fluorescence band in ethanol compared with its monomer. Spatial stacking of phenanthrene units also altered the sp

International audience; Julolidine and benzothiadiazole have been employed separately as building blocks for sensitizers to widen absorption spectrum for dye-sensitized solar cells (DSSCs). We synthesize a new dye combining the two blocks. The DSSCs
