Enhanced blue fluorescence of acridine is achieved in carbene–M–acridine ionic complexes, where M is Cu(I) and Ag(I), approaching 50%. With the help of chiral counter ions, circularly polarized fluorescence of acridine is induced in crystalline state.

Meticulous synthesis methods are crucial for achieving high-purity ZrV₂O₇. Optimized solid-state synthesis can provide sufficient mixing of precursors, while sol–gel methods effectively produce single-phase materials through near-atomic-level mixing.

The carrier capture path via carbon vacancies in 4H-SiC is comprehensively investigated, and a metastable spin-triplet state is found to be a key transition state for carrier recombination.

This approach offers a straightforward strategy to create high-quality, stimulus-responsive chiral metal halide single crystals with large and switchable circularly polarized luminescence for use in anti-counterfeiting and luminescent devices.

Three photoactive COFs containing different acceptors (BO, BT, and BSe) were designed and synthesized. The modulation of acceptors has optimized the intramolecular/interfacial charge transfer processes and improved the photocatalytic performance.
