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%。

A novel diad compound consisting of norbornadiene-steroid- benzophenone (NBD-S-BP) was synthesized and its photochemistry was examined. Irradiation of NBD-S-BP at λ>350nm selectively excited the BP chromophore. After intersystem crossing, the triplet energy of BP was transfered to the NBD group with 21% efficientcy leading to isomerization of the later group to quadricyclane.
