Long-lived luminescent materials possess wide application prospects in various areas, but their constructions still face a huge challenge, especially the achievement solution. Manipulating aggregate is an effective method to attain intriguing luminescence, thus it expected build long-lived In this work, series of new gold(I) complexes were developed by employing unique carbazole and phosphine a...

Fluorescence spectra and lifetimes were determined for 16 synthetic flavylium cation analogues of anthocyanin plant pigments in dry acetonitrile acidified with trifluoroacetic acid (TFA). Phosphorescence was also observed from the lowest excited triplet state all cations at 77 K a rigid TFA-acidified isopropanol glass. The fluorescence quantum yields depend systematic manner on nature position ...

By using an anthryl-substituted 2,2'-bipyridine as a singlet oxygen-reactive ligand, a new class of Ru(II)-bipyridine complex derivatives that can specifically respond to singlet oxygen with remarkable phosphorescence enhancements have been successfully developed.

INHIBIT logic gates based on light-driven β-cyclodextrin pseudo[1]rotaxane were conveniently fabricated in aqueous solution utilizing induced circular dichroism (ICD) and photocontrolled reversible room temperature phosphorescence (RTP) as output addresses respectively.

Menthol (MT) induces strong room temperature phosphorescence (RTP) of 1-bromonaphthalene (1BrN) in aqueous beta-cyclodextrin (beta-CD) suspensions, even under non-deoxygenated conditions. Interestingly, (-)-MT and (+)-MT enantiomers give rise to different phosphorescence intensities, the difference being 19+/-3%. It is argued that the signal can be mainly ascribed to the formation of ternary co...

Directed evolution of p-nitrobenzyl esterase (pNB E) has yielded eight generations of increasingly thermostable variants. The most stable esterase, 8G8, has 13 amino acid substitutions, a melting temperature 17 degrees C higher than the wild-type enzyme, and increased hydrolytic activity toward p-nitrophenyl acetate (pNPA), the substrate used for evolution, at all temperatures. Room-temperature...

We report on five new complexes with the general formula trans-Pt(BODIPY)X(PEt3)2 (), where the platinum(ii) ion is σ-bonded to a 4,4-difluoro-4-bora-3a,4a-diaza-s-indacen-8-yl (BODIPY) and an anionic ligand X(-) (X(-) = Cl(-), I(-), NO2(-), NCS(-), CH3(-)). All five complexes were characterized by multinuclear NMR, electronic absorption and luminescence spectroscopy and by X-ray diffraction an...
