  The optical properties of three bis-benzoxazole derivatives, namely 2,2’-diphenyl-6,6’-bibenzoxazole and its derivatives bearing methyl and tert-butyl groups at the para position, were investigated and compared to those of the corresponding subunits. As expected from the increase of the π-electron conjugated system, the absorption and fluorescence spectra were red-shifted when passing from mono-to

  三个双苯并恶唑衍生物，即2,2'-二苯基-6,6'-二bibenzoxazole的光学性质和它的衍生物轴承甲基和叔丁基组在第位置，并与相应的亚基进行比较。正如从π电子共轭体系的增加所预期的那样，当从单发色团变为双发色团时，吸收光谱和荧光光谱发生红移。三种双-苯并恶唑在溶液中显示出优异的荧光量子产率，但是它们在固态下仅微弱发射，未取代的衍生物实际上甚至不是光致发光的。固态行为是由双发色分子被锁定在非平面构象这一事实来解释的，正如在DFT计算和X射线数据的基础上讨论的那样。
