Abstract
A Ianthanide 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: Structure 2, where: E represents a heteroatom or heteroatom-containing group and R1R8 are independently selected from H, —OH, —NH2, —SO3H, —CO2H, halides, optionally substituted organic groups; and conjugated linking groups which link two of the polydentate ligands of Structure 2 together.

A lanthanide complex comprising 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;

- R1-R8 are independently selected from H;
- —OH, —NH2, X, where X represents a halide;
- —SO3H;
- —CO2H;
- optionally substituted organic groups;
- and conjugated linking groups which link two of the polydentate ligands of structure 2 together.
A method of forming a lanthanide complex comprising combining a lanthanide ion with a ligand-forming molecule having the general formula of Structure 2:

- and
- R1-R8 are independently selected from H;
- —OH;
- —SO3H;
- —CO2H;
