The structures of the crosslinks in supramol. polymer networks play an important role on their properties and functions. Herein, emissive metallacages are used as crosslinks to prepare metallacage-cored polyurethanes. The mech. properties including storage modulus, toughness, Young’s modulus and breaking strength of polymers are greatly enhanced with the increase of crosslinking densities. Moreover, such polymers not only exhibit good fluorescence in the solid state, but also show self-healing and shape memory properties owing to the dynamic reversible non-covalent bonds in their structures. This study not only offers a convenient strategy to prepare metallacage-crosslinked networks, but also explores their applications as self-healing and shape memory materials, which will promote the study of metallacage-cored supramol. networks as smart materials. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Electric Literature of C4H10O3).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Electric Literature of C4H10O3
