Abstract
Metal complexes have a lot of useful applications in organic and organometallic chemistry, catalysis [1], medicine as anticancer pharmaceutics and for drug delivery [2], various biological systems [3], polymers [4] and dyes, separation of isotopes [5], and heavy metals [6], among many other uses. Sometimes they are applied for increasing solubility [7, 8] of classic objects, carbon nanotubes (CNTs), which form bundle-like structures with very complex morphologies with a high number of Van der Waals interactions, causing extremely poor solubility in water or organic solvents. Metal complexes are also able to serve as precursors to fill CNTs with metals [9] or oxides [10], to decorate CNTs with metal nanoparticles [11], as well as to be encapsulated by CNTs [12].
