## Abstract Perylene quinone compounds of natural and syntheitc origin have been investigated for their quantum efficiency of singletβoxygen production (Ξ¦~Ξ~). The results may be interpreted by a qualitative relation between Ξ¦~Ξ~ and the planarity of the sensitizer molecules, highest values (0.8β0.
In benzene and metbauol, the oxygen quenching of all-trans-retinal singlet results in intersystem crossing (enhanced) and energy transfer {to form 'O$ 'A,), both with quantum efficiencies eonsiderabIy less than unity (0.3-0.5). '02" formation from retinol triplet quenching by 302 is closer to quanti
