摘要：

A lead(II) norbornene derivative, Pb(Cp(N))OTf (Cp(N) = 2-(cyclopentadienylmethyl)norborn-5-ene), has been employed along with MTD (MTD = methyltetracyclododecene) to prepare diblock copolymers via ring-opening metathesis polymerization (ROMP). Films of the metal-containing block copolymers that are static cast from benzene contain lead in microphase-separated domains. Treatment of these films with hydrogen sulfide produces nanoclusters of PbS within the microdomains that were characterized by transmission electron microscopy and X-ray powder diffraction. UV-vis absorption spectra of thin film of such materials have a distinct shoulder at approximately 480 nm.
