Four series of multiarmed chiral arylethers carrying two, three, five, or eight side-chains on a variety of aromatic core molecules (2−5) were prepared. The structure and conformation of 2 and 3 (in the solid state) were determined by the X-ray crystallographic analyses. While a pair of alternated (anti) conformers (i.e, up−down and down−up) were found in the crystal of 2, three side-arms in 3 were

The solution-phase synthesis of corannulene has been modified and it is now possible to prepare multi gram quantities of corannulene more efficiently, with considerably less toxic reagents. Cross-coupling of bromocorannulene with TMS-acetylene and phenylacetylene affords novel ethynyl-containing corannulene derivatives. Deprotection of TMS-ethynyl corannulene affords the naked alkyne, which can be cross-coupled with pentafluoroiodobenzene and bromocorannulene to afford the appropriate alkyne derivatives. The photophysical properties of this new and novel family of alkyne-containing corannulene derivatives has been evaluated and all of the new derivatives exhibit low to moderate quantum efficiencies.

purely organic donor–acceptor materials with integrated π‐bowls (πBs) that combine not only crystallinity and high surface areas but also exhibit tunable electronic properties, resulting in a four‐orders‐of‐magnitude conductivity enhancement in comparison with the parent framework. In addition to the first report of alkyne–azide cycloaddition utilized for corannulene immobilization in the solid state
