designed and synthesized. Their structures were characterized by Fourier transform infrared spectroscopy, hydrogen−1 nuclear magnetic resonance, and mass spectrometry. Their photophysical properties including linear absorption, single–photon excited fluorescence, two–photon absorption, and two–photon excited fluorescence, were systematically investigated in various solvents. The relationships between the
设计并合成了一系列具有不同构型的新型多极性对称和不对称N-杂环化合物。通过傅立叶变换红外光谱,氢-1核磁共振和质谱对它们的结构进行了表征。在各种溶剂中系统地研究了它们的光物理性质,包括线性吸收,单光子激发的荧光,双光子吸收和双光子激发的荧光。借助密度泛函理论计算研究了结构与光物理性质之间的关系。
