Introduction of extra carbazole donor to form the D′–A–D type TADF emitters did not disturb the emitting color, but reduced intermolecular interactions and exciton quenching, thus improved the EQE in OLEDs and eliminated efficiency decay.
Blue thermally activated delayed fluorescence (TADF) materials with substantial donors and acceptors skeleton for OLEDs.
Linear acenes, such as naphthalene, can act as acceptors in donor–acceptor type TADF emitters. We demonstrate this strategy through a computational screen and by synthesizing a novel diphenoxazine-substituted naphthalene TADF emitter.
As a novel conceptual synthesis of a metal–organic framework (MOF)-based proton conductor, UiO-66 based on a pyridinedicarboxylic acid phosphate (PyDC-PA) ion pair linker has been developed.
A 1D Cu-MOF was prepared via a hydrothermal method, with the developed Cu-Cu2O@CC heterostructures displaying enhanced activity in the electrocatalytic conversion of CO2 to CH3OH and C2H4 with high FE values of 37.4% and 40.53%, respectively.
