Anionic living polymerization of monomers with photo-electronic properties for control of polymeric nano architectures

Abstract

Block copolymers, 9-ethylcarbazolyl methacrylate (CzMA) with 3-nitro-9-ethylcarbazolyl methacrylate (NCzMA), and styrene with uptically functionalized isocyanates containing disperse red 1 (DRlNCO) and (s)-(-)-2-methylbutanol (MBI), were prepared by anionic polymerization for photo-electronic materials. The living condition of CzMA was found at -78 degreesC for 3 h with diethyl zinc and block copolymers of CzMA with NCzMA were synthesized successfully. The polymers show potential to be used as energy transfer materials in UV and PL spectra. Block copolymers of styrene with optically functionalized isocyanates were also synthesized with high yield and the polymers showed the large optical activity at 476 nm.
