三种类型的三苯甲烷无色腈衍生物结合了一个、两个和三个单氮杂-15-冠-5部分，旨在主要通过分子内静电排斥来实现金属离子络合的光控制。带冠三苯甲烷无色腈的光致变色在很大程度上受到其冠醚部分的阳离子络合的影响。分子轨道计算允许对光致变色冠醚光化学控制金属离子络合的可能性进行一些预测。电喷雾电离质谱、核磁共振波谱和热反应动力学证明了光控制的高效率。
Three types of triphenylmethane leuconitrile derivatives incorporating one, two, and three monoaza-15-crown-5 moieties have been designed to attain photocontrol of metal-ion complexation primarily by intramolecular electrostatic repulsion. Photochromism of the crowned triphenylmethane leuconitriles is influenced by the cation complexation of their crown ether moiety to a considerable extent. Molecular orbital calculations allowed some prediction regarding the possibility of photochemical control of metal-ion complexation by the photochromic crown ethers. High efficiency in the photocontrol has been evidenced by electrospray-ionization mass spectrometry, NMR spectroscopy, and thermal reaction kinetics.
