最近美国威斯康星大学有机化学教授Zimmerman的实验室用单光子计数技术研究了一类刚性分子的光化学能量转移及衰减的理论,它对了解光化学的过程是十分重要的。他们合成了大量的含有电子给体及受体基团的双环[2,2,2]辛烷衍生物,即在桥的一头接α或β-萘基(电子给体),另一头 Recently, Zimmerman’s lab, a professor of organic chemistry at the University of Wisconsin, studied the theory of photochemical energy transfer and attenuation of a class of rigid molecules using single-photon counting. It is important to understand the photochemical process. They synthesize a large number of bicyclo [2,2,2] octane derivatives containing electron donor and acceptor groups, one at the bridge followed by an alpha or beta-naphthyl (electron donor) and the other at the head
