研究了烷基铵离子（Cn+）对吸附在粘土层间的γ-芪（4-（2-苯基乙烯基）吡啶）离子（1）的团簇化和光化学行为的影响。1的聚集体被证明是解离的共吸附的Cn+的分子长度比1长。当共吸附超过1个碳离子时，主要的光反应由环二聚转变为E-Z异构化。有效的激基缔合物发射从插层1显着降低共吸附烷基铵离子。由此产生的浓度依赖性的准分子发射强度很好地模拟由Monte Carlo方法的二维晶格位模型。
Effect of alkylammonium ions (Cn+) has been studied on the clusterization and photochemical behaviors of γ-stilbazolium (4-(2-phenylvinyl)pyridinium) ion (1) adsorbed on clay interlayers. The aggregates of 1 were shown to be dissociated by the coadsorption of Cn+ with molecular length longer than that of 1. The major photoreaction was changed from cyclodimerization to E–Z isomerization on coadsorbing Cn+’s longer than 1. The efficient excimer emission from intercalated 1 was dramatically reduced by coadsorbing alkylammonium ions. The resulting concentration dependence of excimer emission intensity is nicely simulated by a Monte Carlo method for two-dimensional lattice site models.
