Abstract

As a part of the ‘bottom-up’ campaign for the precise preparation of carbon nanotubes, the chemical synthesis of carbon nanohoops is observing rapid progress, with a number of milestone achievements, over the past decade. With simple carbon nanohoops (e.g. cycloparaphenylenes) now no longer elusive targets, this Synpacts article highlights latest synthetic advances to further build up nanohoops’ π-systems. Works reviewed herein include the study explaining the unsuccessful Scholl reaction method, the preparation of a carbon nanohoop consisting solely of hexabenzocoronene units, syntheses of π-extended carbon nanohoops employing the ring-closing metathesis method, and the anthracene photodimerization/cycloreversion method for anthracene-incorporated carbon nanohoop synthesis.
