Tris-bridged [3.3.n](3,6,9)carbazolophanes 1n (n=3–6), which are appropriate model compounds for fully overlapped excimer in carbazole chromophore, have been synthesized and characterized by NMR, X-ray, absorption and fluorescence spectra; 1n showed excimeric fluorescence, whose emission maxima strongly depended on the angles and distances between carbazole rings.
三桥[3.3.n](3,6,9)咔唑并[1n](n=3-6)是咔唑发色团中完全重叠的准分子合适模型化合物,已经通过核磁共振、X射线、吸收和荧光光谱合成并表征;1n显示准分子荧光,其发射最大值强烈依赖于咔唑环之间的角度和距离。
