Two diaryl B- and N-substituted truxene charge-transfer compounds B3 and N3 have been synthesized. The fluorescence intensities of several nonfunctionalized truxene compounds are 1 order of magnitude weaker than that of B3 and N3. To reveal the structure-property correlations, the X-ray structures of B3 and N3 and their precursors 3 and 4 have been determined. The extended molecular dimension, the especially shortened B-C bond, and the improved planarity of B3 can serve as direct structural evidence for the charge transfer.
已合成了两种二芳基 B 和 N 取代的并四苯电荷转移化合物 B3 和 N3。几种未官能化的并四苯化合物的荧光强度比 B3 和 N3 的荧光强度弱 1 个数量级。为了揭示结构-性质的相关性，已确定了 B3 和 N3 及其前体 3 和 4 的 X 射线结构。B3 扩展的分子尺寸、特别缩短的 B-C 键以及改善的平面性可作为电荷转移的直接结构证据。
