Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 19444-84-9, Name is 3-Hydroxydihydrofuran-2(3H)-one, molecular formula is C4H6O3, belongs to tetrahydrofurans compound, is a common compound. In a patnet, author is Pan, Dipika, once mentioned the new application about 19444-84-9, Safety of 3-Hydroxydihydrofuran-2(3H)-one.
Remarkable solvent tunable aggregation caused quenching for fluorochromic chitosan based hydrogel
Fabrication of Hydrogel with solvent tunable fluorescence property has a novel and significant contribution in current research. Herein, chitosan, functionalized with Fluorescein mono-aldehyde, a light emitting molecule forms a smart strong polymeric gel having nanofibrous architect within micro molecular assembly. Multi functionalities, dynamic and reversible non covalent interactions associated with Fluorescent hydrogel have been portrayed in terms of change in photoluminescence with variation of pH, solvent and temperature in the sol phase. The hydrogel exhibits the distinct photoinduced electron transfer (PET) process within itself. Aggregation caused quenching (ACQ) phenomenon occurs in mixing the suitable pH solutions and Pyridine (similar to 20 fold quenching of fluorescence) and Tetrahydrofuran (similar to 325 fold quenching of fluorescence) with the gel solution. The mechanisms of PET and ACQ process have been well explained with quantitative fluorescence measurement and various kinds of host-guest interactions specially pi-pi interactions and H-bondings. Aggregation of solvent molecules with Fluorescent hydrogel networks has been established by dynamic Light scattering (DLS) study. This aggregation based photoluminescence phenomenon would acquire more response for the extensive usefulness in chemical, biological and material research in future. (C) 2020 Elsevier B.V.
