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.

One-dimensional InSeI helical polymorph, with a complex unit cell and directional optoelectronic properties, whose response to linearly polarized light allows identification of the orientation of the van der Waals helical chains from bulk to flake.

Pyrrolo[3,2-b]pyrrole represents a synthetically-simple conjugated scaffold that enables accessing polymers with tailorable properties useful for organic electronics.

Experimental and computational studies of polyurethane derivatives provide new insights into the mechanism of luminescence in non-conjugated molecules. Applications as biological probes and information transmission materials are demonstrated.

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.

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.

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.
