Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 908240-50-6, Name is 2,4-Dichloropyrido[3,4-d]pyrimidine, SMILES is ClC1=NC2=C(C=CN=C2)C(Cl)=N1, belongs to pyrimidines compound. In a document, author is Lee, Chan Hee, introduce the new discover, COA of Formula: C7H3Cl2N3.
Highly effective organic light-emitting diodes containing thermally activated delayed fluorescence emitters with horizontal molecular orientation
In this study, we report new thermally activated delayed fluorescence (TADF) emitters, AcPYM (10,10 ‘-(pyrimidine-2,5-diylbis(4,1-phenylene))bis(9,9-dimethyl-9,10-dihydroacridine)) and PxPYM (10,10 ‘-(pyrimidine-2,5-diylbis(4,1-phenylene))bis(10H-phenoxazine)), by employing donor units at the 2,5-positions of the pyrimidine acceptor unit. The donor-acceptor-donor (D-A-D) units combined in the linear molecular structure of AcPYM or PxPYM enhanced the horizontally oriented alignment, and the horizontal transition dipole moments were realized by up to 87% in the host matrix. Organic light-emitting diodes (OLEDs) containing AcPYM and PxPYM emitters realized external quantum efficiencies (eta(ext)) of 16.8% for blue and green emissions.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 908240-50-6 is helpful to your research. COA of Formula: C7H3Cl2N3.
