本文合成了一个新的降冰片二烯-甾体-二苯酮两元化合物(NBD-S-BP),并研究了它的光化学反应。NBD-S-BP在λ>350nm光的照射下,BP基团吸收光能,系间窜越到三线态后将能量传递到NBD基团并使后者异构化为四环烷,量子效率为21％。
In this paper, a novel norbornadiene-steroidal-benzophenone compound (NBD-S-BP) was synthesized and its photochemical reaction was studied. Under the irradiation of λ> 350nm light, NB group absorbs light energy and transports the energy to the NBD group and makes the latter isomerized into tetracycloalkane. The quantum efficiency 21%.
