An organogold nonlinear optical chromophore includes gold(I) complexed with a benzothiazolyl-substituted fluorophore and optionally an organophosphine ligand or an N-heterocyclic carbene ligand.

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd.sub.3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd.sub.3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

This invention discloses novel ligands for metal complexes. These ligands contain a phenyl with an iso-quinoline (or other type of heterocycles) which are bridged together with a carbon substituted by two aliphatic side chains. The resulting light-emitting metal complexes exhibited high external quantum efficiency and better line shape.
