The hole story: using a new synthetic concept the title hexa-peri-hexabenzocoronenes (HBCs) were synthesized with high atom economy. The coaxial arrangement of the HBCs and arylamines allowed a "double- cable" hole transport (see picture), that is, transp

Following a route described by Müllen et al. we improved the preparation of 1,2,3-tris(3-iodobiphenyl-2′-yl)benzene (4). During the required iododesilylation with iodine monochloride the unexpected formation of a mono-chlorinated compound 6 as major produ

Oligophenylene precursors based on 1,3,5-tris-(2′-biphenyl)ylbenzene (4a) and 1,4-bis-(2′-biphenyl)yl-2,5-diphenylbenzene (5a) were prepared and utilized for efficient hexabenzocoronene (HBC) synthesis by cyclodehydrogenations. Parent HBC 6a was efficiently synthesized from the 1,3,5-tris-(2′-biphenyl)ylbenzene precursor, and novel D3h symmetrical HBCs were prepared from 1,3,5-tris-(2′-biphenyl)ylbenzenes with various substitution types. For the preparation of a tert-butyl containing HBC 7 with D2h symmetry, a two-step cyclodehydrogenation was required because of changes in the spin density distribution.
