Towards large area surface functionalization with luminescent and magnetic lanthanoid complexes

Homogeneous surface deposition of molecules over a large area of the substrate is difficult to achieve but extremely important for proposed applications of magnetic molecules in data storage, information processing or molecular spintronics. In this paper we report a simple method for large area surf...
