Recent advances in the development of luminescent lanthanide-based supramolecular polymers and soft materials

Combination of different properties has always proven effective in the generation of hybrid materials with novel interesting properties. Ln(III) containing materials possessing multiple properties are useful in a wide range of applications. In this article, key and recent examples of metallo-supramolecular polymers in the formation of gels, soft polymeric materials and films are discussed. There is a focus on the use of trivalent lanthanide, Ln(III), ions to provide soft materials with advanced mechanical and luminescence properties for applications in developing electronic- and bio-technologies. This frontier article has been written with the intention of reaching a broad range of readers from various backgrounds such as chemistry, materials chemistry, spectroscopy and biochemistry. Additionally, we evaluate how the unique and versatile properties of such hybrid materials can be tuned and explored to enhance the efficiency, as well as research, for new ones. Finally, an assessment of the current state-of-the-art and our outlook for the future of this field is made.
