### Effect of benzocyclobutadieno-annelation on cyclic conjugation in perylene

#### Abstract

can be significantly altered by means of benzo-annelation. In particular, linear (resp. angular) benzoannelation

was found to decrease (resp. increase) the intensity of cyclic conjugation in R .We now examine

the analogous effect of benzocyclobutadieno-annelation, and show that linear annelation strongly increases

the cyclic conjugation in R, whereas the effect of angular annelation is negligibly small.
