Designing thickness-insensitive cathode interlayers via constructing noncovalently conformational locks for highly efficient non-fullerene organic solar cells

Abstract

Two novel water/alcohol-soluble conjugated polyelectrolytes, PF-TT and PF-BDT, have been designed and synthesized as cathode interlayer (CIL) for highly efficient non-fullerene organic solar cells (OSCs). They both have superior charge...

Tuning Molecular Packing and Boosting Self-Assembling Properties via Ring Fusion Strategy in Naphthalimide-Based A–D–A Conjugated Systems

“…The dihedral angle between the D and A moieties is one of the key factors influencing the electronic structures, photophysical properties, self-assembling behaviors, molecular packing motifs, and charge carrier mobilities of π-conjugated systems . It has been demonstrated that the through-space noncovalent conformational locks strategy has been employed with great success to design highly planar and single bond-linked π-conjugated D–A systems for organic electronics . Meanwhile, the other effective approach for manipulating the dihedral angle of conjugated backbone is the through-bond ring fusion strategy to construct fully fused polycyclic aromatic hydrocarbons (PAHs) .…”
