A novel photo-sensitive telechelic poly(N,N-dimethylaminoethyl methacrylate) with coumarin end (C-PDMAEMA) was prepared with DAMEMA as monomer, coumarin-containing disulfide (C-S-S-C) as a chain transfer agent in the presence of Bu3P and water, AIBN as initiator. The polymer was characterized with 1H NMR, GPC and FTIR spectroscopes. It was found that the polymer can immediately form polymer nano-aggregate in aqueous solution. And the coumarin end group of the polymer can be reversibly photo-dimerized upon 365 and 254 nm irradiation. The hydrodynamic size analysis determined by Malvern Zetasizer Nano-ZS instrument and the TEM observations showed that the average size of the polymer nano-aggregate increased upon 365 nm irradition and decreased upon the subsequent 254 nm light.
