An asymmetric tetradentate metal complex of a N^C^C^N comprising tetradentate ligand has a metal connected to binding sites which are connected to each other via three or four covalent bonds that can be either single or double bonds with bridging linkers reside between C^C and C^N moieties. These linkers result in three-dimension metal complexes with distorted square planar geometries. The four donor atoms coordinate to a metal center. Upon metal binding a 5-6-6 membered metallocycle is formed upon chelation including a first nitrogen donor bond, a first metal-carbon bond, a second metal-carbon bond, and a second nitrogen donor bond. The light emission from these metal complexes can be tuned by the ligand structure over the entire visible spectrum.

The first solid-supported directed aromatic C-H activation/acetoxylation has been successfully developed by using palladium nanoparticles supported on graphene oxide (PdNPs/GO) as a catalyst. The practicability of this method is demonstrated by simple preparation of catalyst, high catalytic efficiency, wide functional group tolerance, and easy scale up of the reaction. A hot filtration test and Hg(0) poisoning test indicate the heterogeneous nature of the catalytic active species.
