Zhang, Xinyu published the artcileSelenium atoms induce organic doped systems to produce pure phosphorescence emission, Computed Properties of 91-02-1, the publication is Chemical Communications (Cambridge, United Kingdom) (2022), 58(8), 1179-1182, database is CAplus and MEDLINE.
A host-guest system is constructed using a guest containing two selenium atoms. The selenium atoms can increase the spin-orbit coupling constant and the conjugation degree, thereby increasing the emission wavelength, and making the materials show only phosphorescence emission.
Chemical Communications (Cambridge, United Kingdom) published new progress about 91-02-1. 91-02-1 belongs to pyridine-derivatives, auxiliary class Pyridine,Benzene,Ketone, name is Phenyl(pyridin-2-yl)methanone, and the molecular formula is C10H15NO, Computed Properties of 91-02-1.
