将咪唑锰（III）卟啉与介观-介观连接双（咪唑锌卟啉）组成的锌卟啉阵列的末端异二聚化，构建了一个巨大的光捕获天线-受体复合物。荧光猝灭滴定结果表明，末端咪唑锰酶-(III)卟啉猝灭激发的锌卟啉被大量中间卟啉分离，中介孔连接的双（咪唑锌卟啉）阵列是一种高效的光收集天线。
A giant light-harvesting antenna-acceptor composite was constructed by heterodimerization of imidazolylmanganese(III)porphyrin to molecular terminals of the zinc porphyrin array composed of meso-meso linked bis(imidazolylzincporphyrin). Fluorescence quenching titration indicated that the terminal imidazolylmanganase-(III)porphyrin quenched excited zinc porphyrin separated by a large number of intervening porphyrins and that the meso-meso linked bis(imidazolylzincporphyrin) array was an efficient light-harvesting antenna.
