Interfacial Coordination and Nanofiber Fabrication of a Tri-Pyridine-Based Derivative with Platinum (II) Ions

Abstract:

In order to investigate the supramolecular assembly and in situ coordination of special amphiphiles with aromatic moieties and without long alkyl chain, a tri-pyridine-based derivative was designed and synthesized. The spreading behaviors of the Langmuir films fabricated from pure water and the subphase containing K2PtCl4 were studied in details. It was found that the compound could form interesting Langmuir films through the interfacial coordination with Pt(II) ions. While well-dispersed nano particles were observed for the films transferred from pure water surface, dense coiled nanofibers could be obtained from Pt(II) subphase, which could be ascribed to the matching direction of coordination and - stacking of aromatic moieties. The transferred LB films were characterized by a series of methods. A rational packing mode was proposed.
