a, Conditions for and possible products of [2+2] photocyloadditions of 1 and 3. b, Emission spectra of four photosensitizers, compared with the triplet energies of substrates 1 and 3, determined from phosphorescence spectra and calculations, see the SI. PL ≡ photoluminescence. c, Product distributions from reaction mixtures with the four photosensitizers. The yields listed are for the regioisomers indicated (drawn in a); the remaining mass is exclusively starting materials and the cis-isomer of 1 for the QD systems, and the same plus minor unidentified side products for the moleculecatalyzed reactions, see the SI. aThe yields in red are calculated in reference to substrate 3, which was added in excess.
