The polymer backbone of 1DOP-Cu(II) consists of phosphonate groups, [-Cu-O3P(CH2)2-PO3-Cu-], at which acid-functionalized groups can serve as a stabilizing shell that are effect in passiviting the surface of nanoparticles. Like trioctylphosphine oxide (TOPO)/trioctylphospine (TOP) species containing phophine oxides (O=P), CdSe particles would be trapped in 1DOP-Cu surface sites to yield a novel nanocomposite that has a unique 1D structure. Firstly, blue-emitting CdSe-doped micelles, spherical assemblies of CdSe nanoclusters into CTAB-micelles, were prepared at room temperature for the first time. The CdSe-doped nanoclusters, well-dispersed in water for a few weeks, were then self-arranged along the 1DOP-Cu polymeric chains to give rise to one-dimensional heterostructures.
