合成了一系列磷原子上带有不同芳基的2，3，4，5-四苯基磷杂环戊烯氧化物，并研究了它们在结晶状态下的荧光性质。这些化合物中的一些显示出强烈的荧光，量子产率为0.75-0.91。这些强烈的发射不仅归因于外围苯环的受限旋转，而且归因于晶体堆积中相邻分子之间的长分子间距离。
A series of 2,3,4,5-tetraphenylphosphole oxides with various aryl groups on the phosphorus atoms were synthesized and their fluorescence properties in the crystalline state were investigated. Some of these compounds showed an intense fluorescence with the quantum yields of 0.75–0.91. These intense emissions are attributable not only to the restricted rotation of the peripheral phenyl rings, but also to the long intermolecular distances between the adjacent molecules in the crystal packing.
