Abstract
Synthesis of norbornene derived phosphonate (1), poly-D-lysine (2), and phopholipid (3) monomers and their complete characterizations are studied. Ring-opening metathesis polymerizations (ROMP) of monomers (1-3) produce well-defined copolymers, CP(1) and CP(2). (1)H NMR along with FT-IR spectroscopy characterization confirms the copolymer formation, while gel permeation chromatography (GPC) analysis suggests the formation of polymers with fairly narrow molecular weight distributions. Upon following the well-known ligand exchange methods these copolymers produce CdSe-bound copolymers, CP(3) and CP(4). Dynamic light scattering and transmission electron microscopy measures the size of these CdSe bound copolymers, while (31)P NMR suggests the formation of CP(3) and CP(4). The results from the experiments of these copolymers on Neuro2A cells suggest that the novel PDL-anchored nanomaterial show their ability to polarize neuronal growth and differentiation.
