Synthesis and Characterization of Highly Conjugated Unsymmetrically Substituted Phthalocyanines

Abstract

<jats:p> Unsymmetric push-pull phthalocyanines with a high degree of conjugation achieved by introducing π-delocalized electron substituents were synthesized by statistical condensation of two different diiminoisoindolines. The characterization and spectroscopic properties of these push-pull phthalocyanines are described. These compounds are targeted for the study of their second-order non-linear optical responses. </jats:p>
