Abstract Two donor-π-acceptor (D-π-A) type 2,2′: 6′,2″-terpyridyl-based organic heterocyclic molecules have been efficiently synthesized via solvent-free Wittig reactions in good yields. One crystal structure of them was determined by single crystal X-ray diffraction determination. The two compounds exhibit sensitive single-photon-excited fluorescence (SPEF) emission with high fluorescence quantum
摘要 通过无溶剂 Wittig 反应以良好的收率高效合成了两种供体-π-受体 (D-π-A) 型 2,2': 6',2"-三联吡啶基有机杂环分子。它们的一种晶体结构是通过单晶 X 射线衍射测定确定的。这两种化合物表现出灵敏的单光子激发荧光 (SPEF) 发射,具有高荧光量子产率和长寿命。研究了双光子激发荧光 (TPEF)、双光子吸收 (TPA) 截面和双光子引发聚合 (TPIP) 微加工实验。实验结果证实它们是有效的有机双光子光聚合引发剂。
