Publikováno v: Journal of materials chemistry C, 2017, Vol.5(27), pp.6777-6789 [Peer Reviewed Journal]

In contrast to monoiridium complexes, the study of diiridium complexes as dopants in phosphorescent organic light-emitting devices (PhOLEDs) is largely unexplored. We now describe the syntheses, detailed NMR analyses, X-ray crystal structures and opt

Publikováno v: J. Chem. Soc., Perkin Trans. 1. :2393-2398

On UV irradiation, β-keto sulfides ArSCH2COPh (Ar = C6F5, C6Cl5) cleaved to radicals ArS· and PhCOCH2˙ which, in one case (Ar = C6F5), were trapped by 1, 1 -diphenylethylene as the adduct PhCOCH2CH2C(Ph)2SC6F5. With diethyl ether as the solvent th

On irradiation (254 nm), 2-(N-methylanilino)-N-phenylsuccinimide (6a) underwent homolysis of the C(2)-N bond to yield fission products N-methylaniline and N-phenylsuccinimide (12), along with the products of ortho- and para-rearrangement 2-[2-(N-meth
