Studying the Role of Anion Ligands in Organometallic Nanoparticles

In recent years the field of single chain organic nanoparticles has attracted the interest of the scientific community due to their promising applications and ease of synthesis.¹ By coordinating metals to a binding polymer matrix under dilute conditions, intramolecular cross-linking could be achieved, leading to single chain collapse and the formation of organometallic nanoparticles (ONPs).²

Polycyclooctadiene (PCOD) can coordinate rhodium chloride dimer complexes, leading to a change in the polymer`s properties; e.g. its conductivity.² The current study focuses on the possible role of the anion bridging ligand in the ONPs with different anions made from PCOD and polybutadiene (PBD).³ This study may enable a better understanding of the conductivity mechanism and will furnish a series of new ONPs with potential novel properties.
