Synthesis of polymeric ladders by topochemical polymerization.
Two polymeric ladders were synthesized by topochemical polymerization. The critical assemblies with multiple reactive centers were characterized by single crystal X-ray diffraction. Approximately 64% and 70% of the mass of the two polymeric ladders can be derived from biomass, respectively.
متن کاملSingle-crystal-to-single-crystal topochemical polymerizations by design.
The polymerization of simple conjugated dienes has long been of interest: polydienes occur throughout Nature, and polyisoprene and its analogues form the basis of entire industries. In contrast, the polymers of similar small conjugated compounds, diacetylenes, trienes, and triacetylenes, are either unknown or laboratory curiosities. For 40 years, the only viable synthetic method for the 1,4-pol...
متن کاملSingle-crystal linear polymers through visible light-triggered topochemical quantitative polymerization.
One of the challenges in polymer science has been to prepare large-polymer single crystals. We demonstrate a visible light-triggered quantitative topochemical polymerization reaction based on a conjugated dye molecule. Macroscopic-size, high-quality polymer single crystals are obtained. Polymerization is not limited to single crystals, but can also be achieved in highly concentrated solution or...
متن کاملFunctionalized, biocompatible coating for superparamagnetic nanoparticles by controlled polymerization of a thioglycosidic monomer.
It is demonstrated that water-soluble, glucosylated poly(pentafluorostyrene) derivatives revealed favorable coating material properties for magnetic iron oxide nanoparticles. To prepare the coating material in high reproducibility and purity as well as in sufficient amounts, a new route of synthesis is established. The preparation and characterization of the glucosylated, tetrafluorostyryl mono...
متن کاملStructural Aspects of the Topochemical Polymerization of Diacetylenes
The present state of knowledge of the topochemical polymerization of diacetylenes is reviewed with regard to structural properties. Principles and mechanisms of topochemical reactions are described. Solid-state polymerization of diacetylenes utilizes the special packing properties of monomer units in their crystals. Rules relating reactivity in the solid-state and packing properties are given a...
