摘要：

A study on thermogravimetric analyses, surface photovoltage (SPV), electron paramagnetic resonance and electrochemical properties comparing a porphyrin dimer with that of corresponding monomer was presented. The SPV intensity is weaker than that corresponding monomer, and with field-induced surface photovoltage spectroscopy (FISPS) reveal that all the compounds are p-type semiconductors. The spectral bands of all the porphyrins corresponded to * transitions. Electrons (or holes) can be trapped on the porphyrins by applying both light and negative (or positive) electric field. The electrochemistry and EPR of the porphyrins show clearly that a - interaction existed between the two macrocycles of the dimer.
