Upgrading the chemistry of π-conjugated polymers toward more sustainable materials

Abstract

While organic electronics are ubiquitous in our daily lives, studies dealing with their environmental impact or their sustainability are scarce.

Molecular design strategies for high‐performance organic electrochemical transistors

“…The aforementioned polymerization methods usually have some disadvantages such as the use of hazardous monomers, toxic solvents, or transition metal catalysts. 40 For environmental protection and bioelectronic applications, several greener polymerization methods have been applied for OECTs, including aldol condensation polymerization for PgNaN 38 (Figure 7D), and direct arylation polymerization for ProDOT(OE)-DMP 41 (Figure 5A). It is believed that polymerization methods will continue expanding to fully release the potential of molecular structure design for high-performance OECTs.…”

Advances in applying C–H functionalization and naturally sourced building blocks in organic semiconductor synthesis

“…Hence, the residual metal in the final products prevent the utilization of the OSMs involving these noble transitionmetals in biomedical applications. 104 To lessen the environmental risk of OSM synthesis and extend the range of OSM application, developing atom-economical synthetic pathways catalyzed by less toxic, more earth-abundant, and more biocompatible first-row transition-metals (e.g., iron, cobalt, nickel, and copper) is imperative.…”

Vinylene-versus azomethine-bridged carbazole-based polymers for light emission and sensor applications

“…The unique mechanical properties and film-forming quality of these polymers also expands the repertoire of tolerant substrates and allow the fabrication of flexible electronic devices [9]. However, the major characteristic justifying the huge interest in semi-conducting polymers is their adjustable molecular structure, benefiting from the richness of the organic synthesis, and therefore their tuneable opto-electronic properties [10]. Among the different conjugated moieties, N and 3,6disubstituted carbazole-based organic semiconductors have found applications in the emerging organic light emitting devices (OLED) field due to their unique optical properties, combined to a high air sensitive stability [11,12].…”
