A new class of all-organic self-powered photoelectrochemical photodetectors (OPEC PDs) based on PDTBT-Qx/PC71BM were successfully constructed and the performance of PDTBT-Qx/PC71BM OPEC PDs was systematically evaluated.
A novel polymer acceptor, PDTBT-Br-T, was synthesized for all-polymer solar cells. It outperforms DTBT-IC in absorption, thermal stability, and molecular stacking, achieving a PCE of 4.44% via enhanced exciton dissociation and reduced recombination.
Direct heteroarylation polymerization (DHAP) has been achieved for P(NDI2OD-T2) with a consistent molar mass using a modified A-B-A monomer and a recyclable heterogeneous SiliaCat Pd-DPP catalyst, for up to four consecutive reuses.
The N-oxide containing conjugated semiconducting polymer is synthesized by direct (hetero)arylation polymerization and exhibit enhanced electron mobility compared to its non-oxide analogous polymer.
Carbon–carbon (C–C) bond formation can be accomplished by various highly chemo-, regio- and/or stereoselective enzymatic reactions, sometimes through the catalytic promiscuity of enzymes.
