Highly Efficient Catalysts for Direct Arylation Polymerization (DArP)

Asian Journal of Organic Chemistry, Journal Year: 2018, Volume and Issue: 7(7), P. 1206 - 1216

Published: May 24, 2018

Abstract Recently, the palladium‐catalyzed direct arylation polymerization (DArP) has emerged as a viable alternative to conventional synthetic means of making π‐conjugated polymers based on catalytic cross‐coupling reactions. The DArP, which proceeds through C−H bond activation, distinct advantage over in terms fewer reaction steps and higher functional group tolerance. We have developed novel catalysts for DArP by using P(2‐MeOC 6 H 4 ) 3 ( L1 P(2‐Me 2 NC L2 ligands. Although common require use strongly coordinating solvents such DMA DMF, our exhibit high activity THF toluene, are good polymers. Thus, we could realize precise synthesis highly head‐to‐tail regioregular poly(3‐hexylthiophene) (HT‐P3HT) donor–acceptor type alternating copolymers (DA polymers) with well‐controlled structures DArP.

Direct (Hetero)arylation: A Tool for Low-Cost and Eco-Friendly Organic Photovoltaics

ACS Applied Polymer Materials, Journal Year: 2020, Volume and Issue: 3(1), P. 2 - 13

Published: Sept. 30, 2020

Organic photovoltaics have attracted much attention in the past few years, mainly due to their ability be fully printed at low cost and large scale. However, organic semiconductors utilized as active layer are typically synthesized using Migita–Stille or Suzuki–Miyaura cross-coupling, which is not efficient may bring toxicity concerns. In search for atom-economical synthesis, direct (hetero)arylation polymerization (DHAP) enables activation of aromatic C–H bonds, both reducing synthetic steps monomers toxic reaction byproducts. this issue, we will discuss recent contributions on synthesis toward mass production photovoltaic materials. The impact DHAP material efficiency addressed compared conventional coupling methods. ongoing improvements discussed, becomes more sustainable higher scale materials observed having quality.
