Abstract: To achieve high-efficiency deep-blue electroluminescence satisfying Rec.2020 standard blue gamut, we developed two TADF emitters, 5-(2,12-di-tert-butyl-5,9-dioxa-13b-boranaphtho[3,2,1-de]anthracen-7-yl)-10,10-diphenyl-5,10-dihydrodibenzo[b,e][1,4]azasiline (TDBA-PAS) and 10-(2,12-di-tert-butyl-5,9-dioxa-13b-boranaphtho[3,2,1-de]anthracen-7-yl)-9,9-diphenyl-9,10-dihydroacridine (TDBA-DPAC). Inherited from their parented organoboron multi-resonance core, both emitters show very promising deep-blue emissions with… read more here.
