摘要
Abstract
Azobenzene polymers have photoresponsive property and get very good application in fields of information storage, photonics, molecular switch etc. The azobenzene star polymer with three- arm was pre⁃pared by atom transfer radical polymerization (ATRP), using the trimethyolpropane as the initiator of nuclear preparation, and azobenzene as the monomer. The structure of polymers were characterized by the infrared spectroscopy (FTIR), hydrogen nuclear magnetic resonance spectrometer (1H- NMR), which showed that the target product was successful y synthesized. The molecular weight and the molecular weight distribution of the polymer was measured by gel permeation chromatograph (GPC), and the results showed that the synthe⁃sized polymer agreed with the "reactive- control able" characteristics. The result of UV spectrophotometer ab⁃sorption of polyazobenzene showed the configuration inversion under light radiation.关键词
