主 题：Starburst Triphenylamine Carbazole Heck reaction Photoluminescence
摘 要：A starburst tripbenylamine cored N-vinyl carbazole （V-Cz） branched compound was designed and synthesized via optimized Heck reaction in a yield of 40-60%. Moderate yield came from decomposition of V-Cz and self-coupling of triiodo-triphenylamine. TCz-TPA adopts a highly twisted propeller conformation by molecular mechanical optimization. It is readily soluble for its highly twisted conformation. Transparent and pinhole free films could be easily fabricated by spin-coating for its starburst structure. It emits blue-greenish light in CH2Cl2 peaked at 460 nm with a narrow full-width at half-maximum （FWHM） of 65 nm. As compared,
