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.
