摘　　要：A kind of azo-containing resin(Azo-R)was synthesized by a simple way through the coupling reaction of 2-nitro-N-methyldiphenylamine-4-diazoresin(NDR)with phenol,and a new covalentely attached multilayer film from Azo-R asH-donor and photosensitive diazoresin,diphenylamine-4-diazoresin(DR)as H-acceptor via H-bonding attraction by self-assembly technique has been fabricated.Following the decomposition of diazonium group of DR under exposure to UVlight,the H-bonds between the layers of the film convert to covalent bonds and the film becomes very stable toward polarsolvents or electrolyte aqueous solutions.Thus the UV-irradiated azo-containing films can be used to measure photocurrentin a conventional three-electrode photoelectrochemical cell using KCl as supporting electrolyte.It was confirmed that theazo-containing multilayer film is responsible for the photocurrent generation.A kind of azo-containing resin(Azo-R)was synthesized by a simple way through the coupling reaction of 2-nitro-N-methyldiphenylamine-4-diazoresin(NDR)with phenol,and a new covalentely attached multilayer film from Azo-R asH-donor and photosensitive diazoresin,diphenylamine-4-diazoresin(DR)as H-acceptor via H-bonding attraction by self-assembly technique has been fabricated.Following the decomposition of diazonium group of DR under exposure to UVlight,the H-bonds between the layers of the film convert to covalent bonds and the film becomes very stable toward polarsolvents or electrolyte aqueous solutions.Thus the UV-irradiated azo-containing films can be used to measure photocurrentin a conventional three-electrode photoelectrochemical cell using KCl as supporting electrolyte.It was confirmed that theazo-containing multilayer film is responsible for the photocurrent generation.
