Donor Acceptor

A library of 237 organic binary/ternary nanohybrids consisting of conjugated polymers donors and both fullerene and non-fullerene molecular acceptors was prepared and screened for sacrificial photocatalytic hydrogen evolution. These donor-acceptor nanohybrids (DANHs) showed significantly enhanced hydrogen evolution rates compared with the parent donor or acceptor compounds. DANHs of <a></a><a>a polycarbazole</a>-based donor combined with a methanofullerene acceptor (PCDTBT/PC60BM) showed a high hydrogen evolution rate of 105.2 mmol g-1 h-1 under visible light (λ > 420 nm). This DANH photocatalyst produced 5.9 times more hydrogen than a sulfone-containing polymer (P10) under the same conditions, which is one of the most efficient organic photocatalysts reported so far. An apparent quantum yield of hydrogen evolution of 3.0 % at 595 nm was measured for this DANH. The photocatalytic activity of the DANHs, which in optimized cases reached 179.0 mmol g-1 h-1, is attributed to efficient charge transfer at the polymer donor/molecular acceptor interface. We also show that ternary donorA-donorB-acceptor nanohybrids can give higher activities than binary donor-acceptor hybrids in some cases.

A recently developed potential model facilitates the separation of initial and final state contributions to chemical shifts in terms of ground state charge transfer and differences in core hole screening charge. The model is applied to the free atom to elemental solid shifts of the elements Na, Mg, Si, and Zn.
