In collaboration with Jasco Corporation we have recently developed an FDCD (fluorescencedetectedcircular dichroic) instrument J-465, which eliminates the photoselection artifacts and efficiently collects the emitted light from the sample solution based on the ideal ellipsoidal mirror principle. Using the J-465 we have investigated a variety of fluorophores with/without polarization for exciton-coupled

Two novel porphyrins, ZnP(SP)CNCOOH and ZnPCNCOOH, bearing cyanoacrylic acid as an anchoring group were synthesized. Porphyrin ZnP(SP)CNCOOH contains a π‐conjugated spacer (SP) for improved electronic communication between the dye and the TiO2 electrode. The spacer bears polyethylene glycol chains to prevent dye aggregation and to enhance solubility of the dye. Electrochemical measurements and theoretical

substituted porphyrin dimers, which contained the thienyl or p-methylphenyl functional groups, have been designed and synthesized for the efficient green dyes for dye-sensitizedsolarcells (DSSCs) applications. The synthesis and characterization of the large conjugated system based on porphyrin dimer derivatives have been investigated through their spectral, electrochemical, and photovoltaic performances

Syntheses of novel 15-substituted-oxophlorins via the MacDonald condensation of diformyl-dipyrroketones and 5-substituted-dipyrromethanes are described. The electronic and steric features of the 15-substituent enable facile control over the oxidation potential of the oxophlorins. Introduction of an electron-withdrawing group efficiently minimizes the formation of oxophlorin π-radicals. Stabilization
