Direct C–H Arylation Derived Ternary D–A Conjugated Polymers: Effects of Monomer Geometries, D/A Ratios, and Alkyl Side Chains on Photocatalytic Hydrogen Production and Pollutant Degradation

Zhao‐Qi Shen,
Guang Zhang,
Kai Yang
et al.

Abstract: Donor–acceptor (D–A) conjugated polymer (CP) featuring high charge mobility and widely tunable energy bands have shown promising prospects in photocatalysis. In this work, a library of ternary D‐A CPs (22 polymers) based on benzothiadiazole, bithiophene, and fluorene derivatives (i.e., fluorene [Fl], 9,9‐dihexylfluorene [HF], and 9,9′‐spirobifluorene [SF]) with and without alkyl side chains, and with 3D geometry are designed and synthesized via atom‐economical direct C–H arylation polymerization to explore the… Show more

“…In general, polymer semiconductor materials are distinguished by their solution processability and film-forming properties. The widely used donor–acceptor (D–A) strategy has played a great role in this dynamic development, which is mainly related to the flexibility to modulate the energy levels of the materials and the significant increase in the diversity of the molecular structure library [ 8 , 9 , 10 ]. Polymers and oligomers of conjugated thiophene have received much attention because of their strong electron-donating ability and are excellent donor units [ 11 , 12 , 13 ].…”
