中文摘要：
设计合成了含咔唑基团的2，2′：6′，2″-三吡啶衍生物W1～W3，运用核磁共振氢谱，核磁共振碳谱对目标化合物进行了表征；研究了W1～W3分子的单光子荧光和双光子荧光光谱，并在密度泛函理论水平上，利用少态模型对W1～W3分子进行初步理论研究，理论计算结果与实验结果得到较好的吻合，为寻找新型双光子材料进行了有益的探索。
英文摘要：
Three new 2,2′：6′,2″-terpyridine derivatives W1-W3 have been designed, synthesised and characterized by ^1H NMR and ^13C NMR. The one-photon and two-photon fluorescence properties of W1-W3 have been investigated, meanwhile at density function theory level we have primarily studied W1-W3 in theory by using few-state model response theory methods. The theoretical results are in good agreement with the available experiment measurements which is an instructive exploration for searching new type of two-photon absorption materials.
