合成了一种含二茂铁基的双环环加成物1，并研究了其作为AgI比率荧光传感器的性能。在1的乙醇水溶液中，银离子的存在导致1：2的金属-配体络合物的形成，该络合物强烈地增强了芘的准分子发射，但却牺牲了单体芘的发射。
A bicyclic cycloadduct 1 bearing a pyrenyl moiety has been synthesized and investigated as a ratiometric fluorescent sensor for AgI. In an aqueous ethanol solution of 1, the presence of silver ion induces the formation of a 1:2 metal-ligand complex, which exhibits a strong intensity enhancement of the pyrene excimer emission at the expense of the emission of monomeric pyrene.
