Photo-induced Living Cationic Copolymerization of Isobutyl Vinyl Ether and Vinyl Ether with Carbazolyl Groups
a fluorescent monomer 2-(9-carbazolyl) ethyl vinyl ether (CEVE) was synthesized in our lab
and its photo-induced living cationic copolymerization behavior with isobutyl vinyl ether (IBVE) was investigated in detail using diphenyliodonium chloride (DPICl)/2
2-dimethoxy-2-phenylacetophenone (DMPA) and zinc bromide (ZnBr
2
) initiating system in dichloromethane solution at 5 ℃
−5 ℃
and −15 ℃
respectively. The living nature of this copolymerization system was confirmed by adding fresh comonomer method after the copolymerization almost finished. In addition
the obtained fluorescent copolymer poly(IBVE-
co
-CEVE) has a low glass transition temperature (
T
g
)
below −10 ℃.
