Incorporating an Alternating Donor–Acceptor Structure into a Ladder Polymer Backbone

Abstract

AbstractIncorporation of the donor–acceptor structure of an alternating conjugated copolymer into a rigid ladder polymer backbone is reported. The resulting ladder polymers show optical features typical of rigid ladder polymers, but present an increased Stokes shift if compared to their non‐polar counterparts. This behavior reflects the occurrence of charge transfer processes during excitation and leads to a positive solvatochromism.
