Tuning the electronic nature of aggregation-induced emission luminogens with enhanced hole-transporting property

Triphenylamine (TPA) is a well-known holetransporting material but suffers aggregation-caused emission quenching in the solid state. Tetraphenylethene (TPE), on the other hand, is an archetypal luminogen that shows the phenomenon of aggregation-induced em

Synthesis, characterization, electrochemistry, and photophysical studies of triarylamine-containing zinc(II) dIImine bis-thiolate complexes

A series of triarylamine-containing Zn(ii) diimine bis-thiolate complexes, [Zn(N^N)(SC6H4Me-4)2] (N^N = 5,5′-bis(N,N-diaryl-4-[ethen-1-yl]-aniline)-2,2′-bipyridine or 1,10-bis(N,N-diaryl-4-[ethen-1-yl]-aniline)-phenanthroline), were synthesized and characterized by 1H NMR spectroscopy, FAB mass spectrometry and satisfactory elemental analysis. Some of the complexes exhibited intense emissions in dichloromethane solution with maxima at 611-685 nm, which originated from both ligand-to-ligand charge transfer [pπ(SR-) → π(diimine)] and intraligand charge transfer [π(triarylamine) → π(diimine)] excited states. The emission maxima were tuned by variation of the donor or acceptor moieties. Thin film emission studies were also carried out on the complexes. All these complexes showed similar Gaussian-shaped emission bands with emission energies similar to those observed in dichloromethane solution at 298 K. In addition, the emission bands displayed concentration-dependent properties in thin-film emission studies.
