Abstract

DNA-CTMA solutions in ethanol doped by various azobenzene compounds were prepared and their absorbance transition by irradiate UV were measured. It was found that trans-cis transition took place in the cases of doped azobenzene and azobenzene-4,4'-dicarboxylic acid diethyl ester(ADCDE). It did not depend for the speed of trans-cis transition of solution which doped both azobenzene and ADCDE to DNA-CTMA with those amount of doping. To the next DNA-CTMA films doped by azobenzene and ADCDE were prepared and their absorbance transition by irradiate UV were measured. Consequently, trans-cis transition took place only by only the films doped azobenzene and was not transferred by the films doped ADCDE. It was found that trans-cis transition of DNA-CTMA films doped by azobenzene (100:1) was faster than PMMA films doped same amount of azobenzene. It is considered that because azobenzene molecules were isolated by intercalation to DNA and the spatial flexibility of azobenzene molecules became large, the speed of trans-cis transition of azobenzene became early compared with the case where it doped to PMMA.
