Substituent effects of porphyrin monolayers on the structure and photoelectrochemical properties of self-assembled monolayers of porphyrin on indium-tin oxide electrode

Article Abstract:

The substituent effects of porphyrin monolayers on the structure and photoelectrochemical properties of the self-assembled monolayers (SAM) on an ITO electrode are examined. There is a larger interaction between the porphyrins without bulky tert-butyl groups.

Electric-field-induced quenching of exciplex fluorescence and photocurrent generation in a mixture of ethylcarbazole and dimethyl terephthalate doped in a PMMA polymer film

Article Abstract:

N-ethylcarbazole (ECZ) was used as an electron donor and at various concentrations to determine the electric field effects on the exciplex fluorescence in a mixture of ECZ and dimethyl terephthalate doped in a poly(methyl methacrylate) polymer film. Results showed that the exciplex fluorescence is quenched by an electric field when the concentration of ECZ is increased. The dependency on the ECZ concentration indicates that there is a efficient hole transport in the electron transfer system.
