BBPOS can be dissolved in THE, CHCl3, xylene, and DMSO. The structure of the monomer and the polymer was confirmed by elemental analysis, NMR, MS and GPC. The optical and electronic properties of the polymer were investigated by UV-Vis absorption spectroscopy and photoluminescence spectroscopy. The results show that the polymer films emit greenish-blue light (lambda(max) = 390 nm) upon UV excitation. Thermo-analysis showed that the glass-transition temperature of the polymer is at 117 degreesC. Moreover, its weight loss was less than 5% on heating to about 349 degreesC under nitrogen atmosphere.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000224563600030&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)804620-62
