Accelerating charge transfer via nonconjugated polyelectrolyte interlayers toward efficient versatile photoredox catalysis

Communications Chemistry, 2021
Conjugated polymers are commonly used as charge conducting systems in photocatalysts, but the use of nonconjugated polymers is less well understood. Here CdS photocatalysts are coated by non-conjugated polyelectrolyte layers, and the influence of the ...

Disorder-induced solitons in conjugated polymers [PDF]

, 1997
We show that weak off-diagonal disorder in degenerate ground state conjugated polymers results in a finite density of randomly positioned kinks (solitons and antisolitons) in the lattice dimerization.

π-Extended Ladder-Type Conjugated Polymers via BN-Annulation

Organic Materials, 2021
Two kinds of ladder-type conjugated polymers were concisely synthesized by the formation of single-stranded conjugated polymers via Stille cross-couplings, followed by nitrogen-directed electrophilic borylations at electron-rich aromatic rings.
