Influence of different acceptor groups in julolidine-based organic dye-sensitized solar cells

Two novel organic dyes containing julolidine as the electron donor and cyanoacetic acid or rhodanine-3-acetic acid as the electron acceptor bridged by bithiophene unit were synthesized. The absorption spectra, electrochemical and photovoltaic properties of the new dyes were extensively investigated. Transient absorption spectra measurements show that both sensitizers are quickly regenerated and the dye cations are efficiently intercepted by the redox mediator. The overall conversion efficiencies of 2.6% and 2.0% were obtained for dye-sensitized solar cells (DSSC) based on the cyanoacetic acid and rhodanine derived dyes, respectively. Compared with the rhodanine terminated dye, the open circuit voltage and the conversion efficiency of solar cell based on the cyanoacetic acid dye are increased about 25% and 30%, respectively. The lower efficiency of solar cell based on rhodanine is mainly resulted from the broken delocalization of the excited state due to the NCH2CO2H anchor, which affects the electron injection from the rhodanine terminated dye to the conduction band of TiO2.

Electrophilicities of symmetrically substituted 1,3-diarylallyl cations

Kinetics of the reactions of nine symmetrically substituted 1,3-diarylallyl cations with different nucleophiles were studied photometrically in dichloromethane, acetonitrile, and DMSO solutions. The second-order rate constants k2 were found to follow the correlation log k2 = sN(N + E). The electrophilicity parameters E of the title cations were derived, using the known values of sN and N of the nucleophilic reaction partners, and compared with the electrophilicities of analogously substituted benzhydrylium ions. Good linear correlations were found between the electrophilicities E and the quantum chemically calculated gas-phase methyl anion affinities of the allyl cations and the σ+ constants of the substituents X.

New intramolecular through-space charge transfer emission: Tunable dual fluorescence of terfluorenes

We have synthesized a series of new terfluorene derivatives, and investigated their novel fluorescence emission behaviors. We have demonstrated a new intramolecular through-space charge transfer emission experimentally and theoretically. This is the first
