The crystal structure of the photoinduced electron transfer (PET) fluoroionophore (3) was clarified by X-ray crystallographic analysis. A molecule 3 sits on a center of symmetry such that two anthracene ring systems are in an anti conformation with respect to one another across the piperazine ring. Intermolecular C-H···π and π···π interactions are observed. It was found that 3 was displayed unique photophysical properties in the presence of guest cations. Complexation of 3 with Zn²+ and NH⁴+ increased the fluorescence intensities of the host by a factor of 20.
通过X射线晶体学分析阐明了光诱导电子转移（PET）氟离子载体（3）的晶体结构。分子3位于对称中心，使得两个蒽环系统在哌嗪环上彼此呈反式构象。观察到分子间的C-H···π和π···π相互作用。发现3在客体阳离子存在下表现出独特的光物理性质。3与Zn²⁺和NH₄⁺的络合使主体的荧光强度增加了20倍。
