Controllable preparation of magnetic carbon nanocomposites by pyrolysis of organometallic precursors, similar molecular structure but very different morphology, composition and properties

Organometallic compounds were synthesized for solid-state pyrolysis to research the structure–property relationship between the precursors and the as-generated magnetic carbon nanocomposites.

Recent progress of magnetic nanomaterials from cobalt-containing organometallic polymer precursors

This review summarizes the recent progress in the syntheses and materials applications of Co-containing organometallic polymers, and mainly focuses on the preparation of magnetic nanostructures from Co-containing organometallic polymer precursors.

Highly transparent and flame-retardant epoxy composites based on a hybrid multi-element containing POSS derivative

Epoxy resin modified with ODMAS comprising a POSS core and sixteen DOPO groups possess high transparency, excellent flame retardant property and enhanced mechanical strength.

Magnetic Hydrogels from Alkyne/Cobalt Carbonyl-Functionalized ABA Triblock Copolymers

A series of alkyne-functionalized poly(4-(phenylethynyl)styrene)-block-poly(ethylene oxide)-block-poly(4-(phenylethynyl)styrene) (PPES-b-PEO-b-PPES) ABA triblock copolymers was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. PESn[Co2(CO)6]x-EO800-PESn[Co2(CO)6]x ABA triblock copolymer/cobalt adducts (10-67 wt % PEO) were subsequently prepared by reaction of the alkyne-functionalized PPES block with Co2(CO)8 and their phase behavior was studied by TEM. Heating triblock copolymer/cobalt carbonyl adducts at 120 °C led to cross-linking of the PPES/Co domains and the formation of magnetic cobalt nanoparticles within the PPES/Co domains. Magnetic hydrogels could be prepared by swelling the PEO domains of the cross-linked materials with water. Swelling tests, rheological studies and actuation tests demonstrated that the water capacity and modulus of the hydrogels were dependent upon the composition of the block copolymer precursors.

Functionalization of graphene by a TPE-containing polymer using nitrogen-based nucleophiles

Through the nitrogen-centered anion reaction of PCT and GO, two new hybrids, RGO-PCT-i and RGO-PCT-s, were successfully prepared and applied as potential optical limiting materials.

Amphiphilic porous polyhedral oligomeric silsesquioxanes (POSS) incorporated polyoxometalate-paired polymeric hybrids: interfacial catalysts for epoxidation reactions

Amphiphilic porous POSS incorporated POM-paired polymeric hybrids were demonstrated to be highly efficient interfacial catalysts for epoxidation of alkenes with H₂O₂.

The partially controllable growth trend of carbon nanoparticles in solid-state pyrolysis of organometallic precursor by introducing POSS units, and their magnetic properties

Organometallic compounds T (without POSS unit) and PT (containing three POSS units) are synthesized for solid-state pyrolysis. When increasing the pyrolysis temperature, the precursors with and without POSS unit show opposite growth trend.
