要旨

The preparation of large-sized carbon nanohoops 1 and 2 was acheieved by Pt-mediated macrocyclization of the diborylated hexa-peri-hexabenzocoronene (HBC) derivative containing four mesityl substituents at the periphery. The temperature-dependent NMR measurements revealed the highly flexible nature of the carbon nanohoop 1. Structural features of 1 and 2 were examined by comparison of photophysical and electrochemical measurements with those of the reference non-strained HBC derivative. Theoretical calculations clarified the possible molecular structure of the carbon nanohoops 1 and 2 and the structures involved in the dynamics.

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.
