A new synthesis of 5,10,15-hexaaryltruxene derivatives has been developed. Experimental observations and theoretical calculations confirmed that the presence of aryl substituents on the sp(3)-hybridized bridge carbon atoms had an effect on the photophysical properties of the truxene core. Interestingly, the cage compound 11 possessing a distorted truxene core was verified by X-ray diffraction analysis; the influence of the peripheral aryl substituents on the photophysical properties of the truxene core was diminished because of its molecular rigidity.
已开发出一种 5,10,15-三芳基并三苯衍生物的新合成方法。实验观察和理论计算证实，sp(3)杂化桥碳原子上芳基取代基的存在对并三苯核心的光物理性质有影响。有趣的是，通过 X 射线衍射分析证实了具有扭曲并三苯核心的笼状化合物 11 的存在；由于其分子刚性，外围芳基取代基对并三苯核心光物理性质的影响减弱。
