Modification and photosensitization of size-quantized particulate CdS film photoelectrodes with bacteriorhodopsin (BR)

Stilbamle and stilbazdium derivatives with dialkylaniline as electron pushing substituents and pyridine or pyridinium substituents BS electron drawing substituents were synthesized and their aggregation behaviors were shdied by UV-Visible, flu+ rescellce and surface photovoltage spectroscopies. Experimental results indicate that the formation of aggregates can be mediated by the electron drawing ability of the substituents introduced for those compounds all bearing strong electron pushing substibent. When the electron drawing substituent is pyridine group, the molecules tend to aggregate in head-btail mannm, whereas the substituent is pyridinium group, the molecules tend to aggregate in face-*face manner. The effect of electron pushing and drawing ability of the substituents on the aggregation behavior is further analyzed in terms of fmn-8 tier orbital interactions.
