A lanthanide complex, method of forming and method of using the lanthanide complex as a near-infrared luminescent material are described. The complex includes at least one lanthanide ion and at least one polydentate ligand derived from a molecule having the general formula of Structure 2:
where: E represents a heteroatom or heteroatom-containing group and R
