要旨

Preferential precipitation of C70 from a toluene solution of C60 and C70 was accomplished with p-trihalohomooxacalix[3]arenes (13·X·X·X) prepared by the reductive coupling of diformylphenols. Heavy halogens, Br and/or I, are essential at the para position of 13·X·X·X for obtaining good yields and selectivities. C70 with up to 92% purity was obtained after the preferential precipitation.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
