设计并合成了具有短间隔子的供体-受体连接的三联体（Fc-ZnP-C-60）1，以获得最长的电荷分离寿命，630 μ s，在室温下报道三联体。三联体1的二茂铁电子供体和富勒烯电子受体连接到与锌卟啉的相对的β，β '-吡咯位置稠合的咪唑环上.激发卟啉后，电子转移到C-60发生在230 ps内，随后空穴转移到二茂铁后500 ps，产生长寿命的电荷分离状态。
A donor-acceptor linked triad with a short spacer (Fc-ZnP-C-60) 1 was designed and synthesised to attain the longest charge-separation lifetime, 630 mu s, ever reported for triads at room temperature. The ferrocene electron donor and fullerene electron acceptor of triad 1 are attached to imidazole rings fused to opposite beta, beta '-pyrrolic positions of the zinc porphyrin. After excitation of the porphyrin, electron transfer to C-60 occurs within 230 ps, followed by hole transfer to ferrocene after 500 ps to produce the long-lived charge-separated state.
