摘要：
Extensive efforts have been put together to create deep-blue fluorophores with desired efficiency of organic light emitting devices (OLEDs). But, deep-blue fluorophores demonstrating high performance for non-doped OLEDs are yet finite in numbers. Herein, a Y-shaped donor-acceptor based fluorophore, 4',4 '',4'''-(1-phenyl-1H-imidazole-2,4,5-triyl)tris(N,N-diphenylbiphenyl-4-amine) (3TPAI) is constructed by integrating imidazole and triphenyl-amine moieties for OLEDs. Non-doped OLED device is constructed by applying 3TPAI as emissive layer which reveals deep-blue light at 443 nm. An EQE of 4.16% is attained with current efficiency (CE) of 5.1 cd/A and a power efficiency (PE) of 2.87 lm/W. High thermal stability is realized with decomposition temperature of more than 500 degrees C (T-d; 516 degrees C). This material reveals the bright future of imidazole based donor-pi-acceptor fluorophores for highly quality non-doped deep-blue OLEDs.
