由于硼原子受到三个大的硬质基团的空间保护，一系列具有各种取代基R的三(苯基乙炔基硬质基)硼烷(R-C(6)H(4)-C1;C-硬质基)(3)B已被制备为空气稳定固体。由于通过硼原子上的 p 轨道进行 p(pi)-pi 共轭，这些化合物表现出独特的光物理性质。特别是，R = NMe(2) 的推挽型衍生物表现出从蓝色到橙色荧光的显着溶剂化显色现象。
A series of tris(phenylethynylduryl)boranes (R-C(6)H(4)-C1;C-duryl)(3)B with various substituents R have been prepared as air-stable solids owing to the steric protection of the boron atom by the three bulky duryl groups. These compounds show unique photophysical properties due to the p(pi)-pi conjugation through the p-orbital on the boron atom. In particular, a push-pull type derivative with R = NMe(2) exhibits a significant solvatochromism of fluorescence from blue to orange colors.
