Pyrrole-Based Organic Dyes for Dye-Sensitized Solar Cells

Series of dipolar dyes containing pyrrole-based conjugate spacers between arylamine donor and the2-cyanoacrylic acid acceptor have been synthesized. These compounds exhibit both π-π*and charge-transfertransition in the absorption spectra. Quantum computation results indicate that the pyrrole moieties havelarger dihedral angles with its neighboring units, leading to..
