Jayabharathi, Jayaraman; Thilagavathy, Shanmugam; Thanikachalam, Venugopal published their research in RSC Advances in 2021. The article was titled 《Blue organic light-emitting diodes with hybridized local and charge-transfer excited state realizing high external quantum efficiency》.Recommanded Product: 523-27-3 The article contains the following contents:
Donor-spacer-acceptor (D-π-A) materials CAPI and CCAPI, with hybridized local and charge transfer (HLCT) emissive states, have been synthesized. The twisting D-π-A architecture promotes the partial separation of HOMO and LUMO, leading to an enhanced % CT component, and the anthracene moiety in CAPI and CCAPI increases the conjugation length, leading to an enhanced % LE component. The non-doped device with CCAPIb shows the blue emission (450 nm) with maximum current efficiency (ηc), power efficiency (ηp), and external quantum efficiency (ηex) of 16.83 cd A-1, 15.32 lm W-1, and 12.0%, resp., as well as exciton utilization efficiency (EUE) of 95% with a luminance of 32 546 cd m-2 and a roll-off efficiency of 0.53%. The new design strategy has great potential for developing high-performance blue electroluminescent materials. The experimental process involved the reaction of 9,10-Dibromoanthracene(cas: 523-27-3Recommanded Product: 523-27-3)
9,10-Dibromoanthracene(cas: 523-27-3) can be sublimated and oxidized to generate anthraquinone. Soluble in hot benzene and hot toluene, slightly soluble in alcohol, ether and cold benzene, insoluble in water.Recommanded Product: 523-27-3
