Synthesis of Photorefractive Star Polymers Containing both Azo Chromophore and Carbazole Units Based Calix4resorcinarene via Combination of RAFT and Click Chemistry
Photorefractive (PR) materials are materials that combine photoconductivity and nonlinear optical (NLO) response to modulate the refractive index of the medium, which have many potential applications such as holographic optical data storage and real-time optical processing 1.Star polymers exhibit physical properties which are distinctly different in many respects to their linear analogues making them ideal material for various potential applications 2.Photorefractive star polymers, which are the simplest structure of numerous possible branched topologies, contain multiple arms with different photorefractive function components connected to a central core via chemical bonds.The particular combination of RAFT and click chemistry is a promising strategy to synthesize the topological structure of the polymers due to both the high degree of end group functionalization and the efficient post-polymerization modification afforded by Cu1-catalyzed azide-alkyne coupling 3.Herein, star-shaped photorefractive polymers, containing both azo chromophores and carbazole groups, were synthesized by click reaction between alkynyl containing cyclic CRA and azido-terminated PCAH-N3 (or PCH-N3) in this work (Scheme 1).
