Cresyl violet perchlorate

Using cresyl violet perchlorate (CVP) as the electron-transfer sensitizer, photo-induced electron transfer of stilbene was also studied (Fig. 6.13). As expected, isomerization of franx-stilbene in ethanol resulted in fran -isomer as main product (Table 6.4). Interestingly, in aqueous media containing dendrimers, CM-isomers were obtained as main products. Additionally, like direct irradiation, dendrimers with smaller cavity size favored c/x-stilbene formation. This observation can confirm the role of dendrimer cavity size.
