19493-44-8, Name is 1-Chloroisoquinoline, belongs to isoquinoline compound, is a common compound. Formula: C9H6ClNIn an article, once mentioned the new application about 19493-44-8.
The present invention provides a compound of formula (I) indicated by the red light metal complex: wherein m is 2, n is 1 or m is 3, n is 0; R1 Independent of the selected from C1 – C10 alkyl, C1 – C10 substituted alkyl, C6 – C10 aryl group; R2 Independent of the selected from C1 – C10 alkyl, C6 – C25 aryl, C6 – C25 heterocyclic aryl; Ar is C6 – C30 heterocyclic aryl group. The invention uses the aromatic group as the main group connection wu, triphenylamine as capping group at the same time, the two the synergistic effect of both and triphenylamine steric effect of reducing the dye interaction force between molecules, reduces the triplet excitons of solid film self-quenched phenomenon, at the same time to the electronic effect of the triphenylamine strong HOMO energy effective to increase, thereby reducing the band gap, spectrum red shift. The invention preparation of red to dark red light phosphorescence iridium complex in general better soluble in a solvent, is favorable to the preparation solution in the processing device, the preparation of the organic electroluminescent device has a higher luminous efficiency and power efficiency.
