electrochemical property are studied in detail. The unique herring-bone arrangement which is revealed by the X-ray crystallography should account for the intense solid-state fluorescence. The theoretic calculations are employed to clarify the origin of the large Stokes shift and the positive solvatochromism in view of the geometric relaxation and the transition feature.

三氟化硼醚合物存在下分子内缩合得到标题化合物,并用1H NMR、13C NMR、IR表征。 , 和 EI-MS。详细研究了基于溶液和固态的荧光以及电
化学性能。X 射线晶体学揭示的独特人字形排列应该解释强烈的固态荧光。根据几何弛豫和跃迁特征,通过理论计算阐明了大斯托克斯位移和正溶剂致变色的起源。
