Three novel dimeric porphyrins bridged by spirobi-indan spacers have been synthesized; for these monozinc mixed porphyrins (Zn-P–H2-P), the rates of intramolecular singlet excitationenergytransfer from Zn-P to H2-P were determined by picosecond time-resolved fluorescence spectroscopy.
合成了由螺双茚满间隔基桥接的三种新颖的二聚卟啉。对于这些单锌混合卟啉(Zn- P –H 2 - P),通过皮秒时间分辨荧光光谱法确定了分子内单重态激发能从Zn- P转移到H 2 - P的速率。
