Abstract
Chromophoric initiator containing pyrene moiety was synthesized and was used to the normal and photo-induced ATRP of various monomers to obtain the flourscent polymer. These well-controlled dye-labeled polymer showed a low polydispersity (Mw / Mn = 1.20 ~ 1.30), and could form the diblock copolymers. Photo-induced or Photo-mediated ATRP was performed in our study. Photo-induced ATRP is an efficient or economical method for methyl acrylate, methyl methacrylate and styrene polymerization. The photo-mediated polymerization could use the handheld UV light as the low energy source to replace the traditional oil bath or the high temperature condition. Besides, during the photo-induced ATRP process we found the poly(styrene) had the strongest fluorescence than other polymers. For this reason, we compared the fluorescence of dye-labeled polymer by ATRP and photo-induced ATRP. Moreover we designed some control experiments to illustrate and explain the strongly fluorescent effect in poly(styrene) by photo-induced ATRP. Meanwhile, we used the homo or diblock copolymer with chromophore to form the nanotube polymer structure by AAO (anodic aluminum oxide) template. The nanotube structure could be observed by the SEM (Scanning electron microscopy) and the fluorescence of nanotube polymer structure was also discussed.
