Subnanometer-Diameter Wires Isolated in a Polymer Matrix by Fast Polymerization

Abstract: The preparation and analysis of inorganic-organic polymer nanocomposites consisting of inorganic nanowires and multiwire "cables" in a random-coil organic polymer host is reported. Dissolution of inorganic (LiMo3Se3)n wires in a strongly coordinating monomer, vinylene carbonate, and the use of a rapid polymerization in the presence of a cross-linking agent produce nanocomposites without phase separation. Polymerization of dilute solutions yields a material containing mostly (Mo3Se3(-))n mono- and biwires, 6 to… Show more

“…In polar solvents, 1D host phases such as MMo 3 Se 3 (M = Li, Na) form colloidal systems containing monodisperse, negatively charged condensed cluster chains (Mo 3 Se 3 ). Such systems are also of interest for intercalation research [184].…”

“…Utilizando-se matrizes template inorgânicas os (nano) compósitos obtidos possuirão características híbridas, podendo apresentar melhores propriedades mecânicas, térmicas, químicas, elétri-cas, entre outras. O interesse particular na investigação de materiais (nano) compósitos pode ser constatado na literatura onde observa-se um significativo aumento no número de publicações nesta área nos últimos anos [57][58][59][60][61][62][63][64][65] . Assim o método template consiste em reações do tipo hospedeiro/convidado onde o convidado (guest) é sintetizado em um hospedeiro (host) com tamanho e forma de poros controlados, possibilitando a organização e estabilização de materiais, em micro e nanoescala, sem provocar modificações substanciais na estrutura do hospedeiro.…”

“…The isolated wires are easily obtained from the bundles by using a highly polar solvent. 13 Although these materials are in bulk crystalline form, they show onedimensional ͑1D͒ properties due to the existence of long Y 6 X 6 atomic chains. Chew et al 14 have used the nuclear magnetic-resonance spectroscopy to probe the electronic structure of the M cation sites in M 2 Mo 6 Se 6 , M = ͑Li, Rb, Cs, In͒.…”
