Abstract: A novel photosensitive telechelic polymer C-PDMAEMA was prepared using 2-(dimethylamino) ethyl methacrylate (DAMEMA) as a monomer, azobisisobutyronitrile (AIBN) as inititon, coumarincontaining disulfides (C-S-S-C) as a chain transfer agent in the presence of tributyl phosphine (Bu3P) and water. Characterization was carried out using 1H-nuclear magnetic responance (1H-NMR), gel permeation chromatography (GPC) and Fourier transform infrared (FTIR) spectroscopy. It was found that the coumarin can form a host-guest inclusion complex with β-CD in aqueous solution. The UV-Vis and fluorescence spectra showed that only a 1:1 complex was formed with an inclusion complex K=(1.270±0.062)×104 L· mol-1. The irradiation experiment showed that this host-guest inclusion might have a very small effect on the photodimerization of coumarin end groups.
