Synthesis, Properties, and Derivatization of Poly(dihydrogermane): A Germanium-Based mostlyPolyethylene Analogue
Polygermanes are germanium-based analogues of polyolefins and possess polymer backbones made up catenated Ge atoms. Within thecurrent contribution we report the preparation of a germanium polyethylene analogue, polydihydrogermane (GeH2)n, by way of two easy approaches that contain topotactic deintercalation of Ca ions from the CaGe Zintl section.
The ensuing (GeH2)n possesses morphologically dependent chemical and digital properties and thermally decomposes to yield amorphous hydrogenated Ge. We additionallypresent that the ensuing (GeH2)ngives a platform from which functionalized polygermanes may bereadyby way of thermally induced hydrogermylation-mediated pendant group substitution.
Coarse-grained simulation of the aggregation and constructionmanagement of polyethylene nanocrystals
Polyethylene (PE) telechelics with carboxylate practicalteams at each ends have been proven to assemble into hexagonal nanocrystal platelets with a topoutlined by their chain size in primary CsOH-solution. On this coarse grained (CG) simulation research we present how properties of the practicalteams alter the aggregation and crystallization habits of these telechelics. Systematic variation of the parameters of the CG mannequinconfirmed that vitalcomponents which managementnanoparticle stability and construction are the PE chain size and the hydrophilicity and the steric demand of the pinnacleteams.
To characterize the aggregation course of we analyzed the quantity and measurement of the obtained aggregates in addition to intramolecular order and intermolecular alignment of the polymer chains. By comparability of CG and atomistic simulation information, it could possibly beproven that atomistic simulations representing totally different chemical techniquesmay be emulated with particular, totally different CG parameter units. Thus, the outcomes from the (generic) CG simulation fashionscan be utilizedto elucidate the impactof various head teams and totally different counterions on the aggregation of PE telechelics and the order of the obtained nanocrystals.
