Thanikachalam, Venugopal; Jeeva, Palanivel; Jayabharathi, Jayaraman; Ramanathan, Periyasamy; Prabhakaran, Annadurai; Saroj Purani, Elayaperumal published the artcile< Nondoped Blue Organic Light Emitting Devices with Donor-π-Acceptor Derivatives as the Emissive Material>, Formula: C9H7BrO, the main research area is blue organic light emitting device MO photoluminescence solvent polarity.
Blue emitting devices based on donor-linker-acceptor geometry such as p-methoxynaphthylphenanthroimidazole-phenyl-phenylbenzenamine (TPA-MPI) and p-methoxynaphthylphenanthroimidazole-styryl-phenylbenzenamine (TPA-MPS) were synthesized and characterized. Due to the rigid mol. backbone composed of phenanthro[9,10-d]imidazole (acceptor), Ph (TPA-MPI) and styryl (TPA-MPS) spacers, and triphenylamine (donor), these compounds exhibit good thermal stability. The nondoped device based on TAP-MPS exhibits higher efficiencies, 1.73 cd A-1 (ηc), 1.46 lm W-1 (ηp), and 2.11% (ηex). The higher efficiency is attributed to the coemission from the intercrossed excited state of the emissive layer.
Industrial & Engineering Chemistry Research published new progress about Band gap. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Formula: C9H7BrO.
