要旨

A kind of o-carborane-based macrocycle was synthesized via oxidative coupling of acetylene-terminated o-carborane precursors. Single crystal X-ray diffraction analysis unambiguously revealed their unique porous supramolecular structures, which displayed micropore characteristics. Interestingly, the crystal structure of macrocyclic CBMC-2 formed through non-covalent interactions shows packing parameters corresponding to the ideal polymerization parameters. UV-vis, DSC and X-ray analyses indicated that the crystals of macrocycle CBMC-2 could undergo diacetylene topochemical polymerization inside the solid by heating. This was confirmed using Raman spectroscopy and solid-state 13C NMR spectroscopy. This work provides a method for synthesizing carborane supramolecular polymers.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
