Four series of linear tricyclic and quadricyclic heterocyclic derivatives related to oxolinic acid have been prepared: 1H-pyrido[3,4-g]quinolin-4-ones (1), 1H-pyrido[3,2-g]quinolin-4-ones (2), 1H,11H-pyrido[3,2-b] acridine-4,6-diones (8)and 1H,10H-indolo[3,2-g]quinolin-4-ones (10).
Effects of Deuterium Isotopes on Pt(II) Complexes and Their Impact on Organic NIR Emitters
We have developed general guidelines for the effect of deuteriumisotopes on the NIR emission efficiency of Pt(II) complexes and common organic NIR emitters. Also, in this study the NIR OLED based on deuterated Pt(II) complex DPh-3-f emitter attains 796 nm electroluminescence with EQEmax of 16.6 % and radiance of 32,279 mW Sr−1 m−2, which sets new records for NIR OLEDs of >750 nm.
