Synthesis and isolation of a homodimer of cadmium selenide nanocyrstals

By size-selective precipitation homodimeric CdSe nanocyrstals could be isolated from a mixture of oligomers formed when monodisperse CdSe nanocrystals were linked by the bifunctional organic ligand, bis(acyl hydrazide). TEM images revealed a reproducible separation between CdSe particles of approximately a quarter of the particle diameter. This distance is consistent with the physical dimensions of the linker.

Oxidative coupling polymerization of bishydrazide for the synthesis of poly(diacylhydrazine): Oxidative preparation of oxidatively degradable polymer

The oxidative coupling polymerization of bishydrazide is successfully performed to form poly(diacylhydrazine) (PDAH), which is an oxidatively degradable polymer. Oxone is an effective oxidant, and a mixture of an aprotic polar solvent, water, and acetonitrile or N,N-dimethylacetamide is necessary as the solvent. On treatment of PDAH with sodium hypochlorite solution or hydrogen peroxide, the PDAH is rapidly oxidized and degraded to the corresponding dicarboxylic acid. When hydrogen peroxide is used as the oxidant, the addition of acetonitrile and potassium carbonate is necessary for effective degradation. PDAH exhibits high thermal stability in air and a high Tg value. No oxidation is observed in air. Thus, PDAH is an oxidatively degradable high-performance polymer that is stable toward oxygen.
