Non-doped active layer, benzo[k]fluoranthene-based linear acenes, for deep blue- to green-emissive organic light-emitting diodes

This work studies a series of fluorescent materials, benzo[k]fluoranthene- based linear acenes, and uses these materials directly as the non-doped active layer to fabricate deep blue- to green-emissive organic light emitting diodes (OLEDs). Experimental results indicate that benzo[k]fluoranthene-based linear acenes with different substituents in pristine films have a wide range and strong intensity of the luminescence spectra. The substituents of benzo[k]fluoranthene derivatives modulate the lifetime of the excited state and PL spectra of excitonic, excimer or both emissions in the solid state. Controls of emission spectra are exploited in fabricating high-performance non-doped deep blue to green OLEDs with electroluminescence in the deep blue region (420-460 nm), green region (480-580 nm) or both (430-580 nm).

Photophysical, electrochemical, and electrogenerated chemiluminescent properties of 9,10-dimethyl-7,12-diphenylbenzo[k]fluoranthene and 9,10-dimethylsulfone-7,12-diphenylbenzo[k]fluoranthene

A newly synthesized light emitting compound 9,10-dimethylsulfone-7,12-diphenylbenzo[k]fluoranthene (DSDPBF) and its synthetic intermediate 9,10-dimethyl-7,12-diphenylbenzo[k]fluoranthene (DMDPBF) were studied to evaluate how the addition of weak electron donating methyl groups and the subsequent addition of an electron withdrawing sulfone group affect the photophysical and electrochemical Properties as well as the rate of radical cation coupling of the parent compound, 7,12-diphenylbenzo[k]fluoranthene (DPBF). Although the photochemical and electrochemical properties of DSDPBF were more similar to the unsubstituted DPBF than to the DMDPBF, there was a substantial decrease in the quantum efficiency upon addition of the electron-rich sulfone group which was not observed upon addition of the methyl groups. On the other hand, the rate of radical cation coupling or dimerization observed upon electrochemical oxidation varied significantly. The addition of the electron donating methyl groups decreased the reactivity of the radical cation resulting in a 40 times slower rate of dimerization than that observed for the unsubstituted benzo[k]fluoranthene, whereas the addition of the electron withdrawing sulfone group to the methyl groups increased the radical cation reactivity resulting in a rate of dimerization that was 3 times faster than the unsubstituted parent compound. As a result, the electrogenerated chemiluminescence emission spectrum obtained from the annihilation reaction between the radical anion and radical cations of DSDPBF was dominated by emission from the dimer at 589 and 621 nm instead of emission from the monomer at ca. 485 nm.
