As a monomeric ligand for a soluble 1D coordination polymer, a benzyl-ether based dendrimer having a rigid 4,4'-bispyridine ligand at the focal point has been synthesized and the coordination chemistry with Pd(II) investigated by nuclear magnetic resonance, ultraviolet-visible and fluorescence spectroscopies, gel permeation chromatography measurement, and X-ray photoelectron spectroscopy. As a result, it was found that the synthesized dendrimer forms a stable, soluble Pd(II) coordination polymer with rough estimation of degree of polymerization of 10 in organic solvents. Furthermore, through the coordination polymer we attempted to link fourth-generation poly(amidoamine) dendrimers (PAMAM) individually immobilized on mica and confirmed the interconnection of the PAMAM through coordination polymers by atomic force microscopy.
