中文摘要:

二系列 monotailed 卟啉,Cobalt-5-{4-[-(1-adamantaneamino) alkyloxy ]苯基} -10,15,20-triphenyl porphyrinate ( CoPC n 一, n=4,5,6 )并且Nickel-5-{4-[ -(1-adamantaneamino)alkyloxy]phenyl}-10,15,20-triphenyl porphyrinate ( NiPC n 一, n=4,5,6 ),被综合,在哪个卟啉一半经由灵活的烃链被连接到 1-adamantanamine 。在这些施主底层和 mono-6-p-nitrobenzoyl 之间熄灭的荧光 -- cyclodextrin (NBCD ) 详细被学习。不同荧光熄灭发生在这些超分子的系统。这熄灭在在卟啉施主和 cyclodextrin 领受人之间的超分子的集会内被归因于 photoinduced 电子转移(宠物) 。详细 Stern-Volmer 常数被测量,他们被划分成熄灭常数和静态的有约束力的常数的动态 Stern-Volmer。在卟啉子单元和 NBCD 之间的 PET 相互作用是确实有效的,这被表明。

英文摘要:

Two series monot ailed porphyrins, Cobalt-5- {4- [ω- (1-adamant aneamino) alkyloxy] phenyl }- 10,15,20-triphenyl porphyrinate (CoPCnA, n=4,5,6) and Nickel-5-{4-[ω-(1-adamantaneamino)alkyloxy]phenyl}-10,15.20- triphenyl porphyrinate (NiPCnA, n=4,5,6), were synthesized, in which the porphyrin moiety was connected to l-adamantanamine via a flexible hydrocarbon chain. The fluorescence quenching between these donor substrates and mono-6-p-nitrobenzoyl-β-cyclodextrin (NBCD) was studied in detail. Distinct fluorescence quenching occured in these supramolecular systems. This quenching was attributed to the photoinduced electron transfer (PET) inside the supramolecular assembly between the porphyrin donors and cyclodextrin acceptors. Detailed Stern-Volmer constants were measured and they were partitioned into dynamic Stern- Volmer quenching constants and static binding constants. It was demonstrated that the PET interaction between the porphyrin subunits and NBCD is indeed effective.
