摘要
金丝桃蒽酮素(HYP)是有多个羟基的醌类衍生物.在极性溶剂乙腈中,电子给体N,N-二乙基苯胺和电子受体甲基紫精、蒽醌均能有效猝灭其荧光.说明它既具有酚羟基的给电子性能,又有醌类化合物的受电子性能.HYP与平面构型的蒽醌可能形成基态复合物,以不同的方式与其发生光致相互作用.
ypericin(HYP) is a derivative of polyhydroxy substituted perylenequinones. In acetonitrile, the fluorescence of HYP can be quenched by electron donor: N,Ndiethylaniline and acceptors: methyl viologen, anthraquinone, indicating that HYP can act either as a electron acceptor like quinones or as a electron donor like phenols. HYP maybe forms charge transfer complex in ground state with anthraquinone which has a plane configurition and interacts with it in the different way.
