Two‐Dimensional Conducting Polymers: Synthesis and Charge Transport

Abstract

Current technological advances and prolific endeavors have entrenched two-dimensional conducting polymers as the rapidly emerging interface across a diversity of functional materials for flexible electronics, sensors, ion-exchange membranes, biotechnology, catalysis, energy storage, and conversion. Rational design and fabrication of polymeric nanostructures enriched with well-ordered geometry are appealing and endorse significant impact on their inbuilt electrical, optical, and mechanical properties. In particular, recent interest in controlled hierarchical assembly of monomers/oligomers proved the free-standing sheet-like structures with exotic features of high conductivity and flexibility. Yet, the ongoing research to make nanometer-thick polymers suffers from limitations to access large-area, mechanical stability, and high-range internal ordering. In this perspective, we focus on the radical approaches that highlight confinement-entitled features of two-dimensional polymeric materials correlating to their interface or template-assisted synthesis, structure-property relationship, charge transport properties, and future scopes for relevant practical enactments.

Porous pathways: Exploring the future of conducting polymers

“…Self-supporting 2D CPs are essential for electronic and electrochemical applications. 37 Their planar configuration not only enhances the charge transport efficiency but also allows the integration of CPs into flexible and wearable devices due to their lightweight and thin characteristics. Moreover, the presence of interconnected pores spanning the 2D structures enables efficient diffusion of molecules and ions.…”

“…Furthermore, we investigate methods to achieve highly crystalline 2D-like CPs with porous morphologies and to produce self-supporting films. Promising future avenues, such as ice-assisted methods [34][35][36] and interfacial polymerization, [37][38][39][40] are extensively discussed. We also show some successful applications of these 2D-like porous CPs in practical devices.…”
