Abstract: Biphenylene is a well-characterized compound that includes the union of both aromatic and antiaromatic units: benzene and cyclobutadiene, respectively. In this work, we extend this structural theme to acene analogues with a cyclobutadiene linkage in… read more here.

Abstract: To gain insights into the coupling of conformational and electronic variables, we exploited steric hindrance to modulate a polycyclic skeleton with a bent conformation in the S0 state and a twisted conformation in the S1… read more here.
