A novel push–pull compound with a 1,3-bis(dicyanomethylene)indan-2-ylidene moiety as an acceptor subunit has been prepared along with its two derivatives. These molecules are severely distorted from its planar structure and in solution undergo dynamic interconversion between bent structures. The structural features and UV–vis spectroscopic results indicate that the zwitter-ionic nature of the molecule
一种具有1,3-双(二氰基亚甲基)茚满-2-亚烷基部分作为受体亚基的新型推挽化合物及其两种衍生物已被制备出来。这些分子从其平面结构严重变形,并在溶液中经历弯曲结构之间的动态相互转换。结构特征和紫外可见光谱结果表明,该分子的两性离子性质在基态下得到了增强,这在理论上也得到密度泛函计算的支持。
