Spectroscopic (λmax and ET) and photochemical (quantum yield of benzocyclobutenol formation ΦCB and Stern-Volmer quenching constant with diene KSV) properties for meta-substituted polyketones 1b-f, 2, and 5b, pa
Photocyclization Reaction and Triplet Lifetime of Hindered o-Alkyl Benzophenones
Ito, Yoshikatsu,Umehara, Yasutoshi,Yamada, Yutaka,Matsuura, Teruo
, p. 1160 - 1161 (2007/10/02)
The triplet lifetimes of hindered 4'-substituted-2,4,6-tri-isopropylbenzophenones decrease (increase) with the increasing electron-donating (withdrawing) ability of the ring substituents; this is the opposite effect to that expected from the rate of the i
