Paragraph 0152; 0153, (2019/04/08)
A compound comprising a first ligand LA having a Formula selected from: is disclosed. In the Formulas rings B and C are 5-membered or 6-membered aromatic or heteroaromatic ring; Z1, Z2, X1, X2, X3, X4, X5, and X6 are each C or N, but X1, X2, X3, or X4 is C when it forms a direct bond to Z2; Y is selected from CRR′, NR′, O, S, and Se; R, R′, RA, RB, RC, and RD are each selected from a variety of substituents; the ligand LA is coordinated to a metal M by the dashed lines, and optionally to other ligands. Organic light emitting devices and consumer products containing the compounds are also disclosed.

Compounds of type A are fluorescent, if the donator groups, like NMe2, OMe, SMe and PR2, and the acceptor groups, like R'P(O)X, SO2R' and CO2R', are linked to different nuclei of the naphthalin ring system.The chemoselectivity of the electrophilic phosphoryl compounds P(O)X to nucleophiles like ROH, RNHR' and RSH is determined by the nature of the leaving group X responsible for different reaction mechanism.Phosphoryl groups with X = Cl attack predominantly R-NHR'- groups; phosphoryl compounds with X = F and OC6H4NO2(p) are ROH-selective.In this publication compounds of type A are presented, in which fluorescence and chemoselectivity are combined by structure in one molecule.These compounds are important analytic reagents (prove of the functional groups in the active site of enzymes) and as protective groups in the synthesis of natural products like peptides.
