A cluster type of electron acceptor, TPB, bearing four α-perylenediimides (PDIs), was developed, in which the four PDIs form a cross-like molecular conformation while still partially conjugated with the BDT-Th core. The blend TPB:PTB7-Th films show favorable morphology and efficient charge dissociation. The inverted solar cells exhibited the highest PCE of 8.47% with the extraordinarily high Jsc values (>18 mA/cm(2)), comparable with those of the corresponding PC71BM/PTB7-Th-based solar cells.

Benzoate anions-intercalated NiFe-LDH nanosheet on carbon cloth (BZ-NiFe-LDH/CC) behaves as a highly efficient and durable electrocatalyst for alkaline seawater oxidation. In alkaline seawater, it attains the current density of 500 mA cm -2 at a low overpotential of 610 mV for 100-h uninterrupted electrolysis with no obvious structural change, reflecting significantly boosted activity and resistance toward chlorine species corrosion.
