摘要
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 ( NB D - 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.
