Reference of 1826-11-5. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1826-11-5, Name is 2-Phenylthiazole
Patterns of variations in spectral-luminescent and radiation generation properties of new mono- and bicyclic phenyl-, furyl-, and thienyloxazoles and some of their derivatives are considered.The compounds can fluoresce, and some of them are capable of generating radiation at wavelengths of 300 to 370 nm with gamma ca. 0.0001-0.2 quantum yields.Increasing the number of structural subsystems shifts the intense long-wave absorption and fluorescence bands to the red.This is accompanied by an increase in the extinction coefficient of the absorption band.Simultaneously, the gamma values in the ultraviolet region increase by three to four orders of magnitude, the fluorescence lifetime decreases by one order of magnitude, the cross section of stimulated radiation increases, and the pumping pulse width for self-excitation of an active medium increases to several nanoseconds.The possibilities of quantum chemically controlling the properties of excited states and transitions in the medium-UV region are considered.
