In this work, carbon nanodots were synthesized using grape skin as raw material by one step hydrothermal method under optimized experimental conditions. The carbon nanodots were characterized by TEM, fluorescence, UV, IR and XPS. The average particle size of the carbon particles was 4.0±1.5nm. When excited at 430nm, the carbon nanodots showed strong green fluorescence of 522nm which was dependent...
In this work, the interaction of jatrorrhizine with human serum albumin (HSA) was studied by means of UV–vis and fluorescence spectra. The intrinsic fluorescence of HSA was quenched by jatrorrhizine, which was rationalized in terms of the static quenching mechanism. The results show that jatrorrhizine can obviously bind to HSA molecules. According to fluorescence quenching calculations, the bimolecular...
A novel open-bowl pyramidal compound cyclotriveratrylene–carbazole (CTV–CZ) was designed and synthesized. Its absorption and emission spectroscopic properties in different organic solvents were characterized. Three absorption peaks of CTV–CZ around 235nm, 260nm and 290nm were observed. The fluorescence emission peaks were at about 353nm and 368nm using a solution of ∼10 −7 M CTV–CZ. The intermolecular...
