Abstract
Crystalline 1-(2,6-dichlorophenyl)-4-phenyl-trans,trans-buta-1,3-diene (5) displays excimer emission while the crystalline nonchloro analog (2) and solutions of both compounds exhibit only monomer emission. Solid 5, unlike 2, undergoes reaction on irradiation yielding only one of two topochemically-allowed, mirror-symmetric photodimers.
