Production of per-alkylated coronene for use in electrical or optical components, e.g. field-effect transistors, involves regiospecific catalytic hydrogenation of corresponding hexa-peri-hexa-benzocoronene

摘要

A method for the production of per-alkylated coronenes (I) involves the regiospecific catalytic hydrogenation of hexa-peri-hexa-benzocoronenes (II) on a hydrogenation catalyst. Independent claims are also included for (1) per-alkylated coronenes (I) obtained by this method (2) per-alkylated coronenes of formula (I) (3) arrangements of (I). R1-R18 = H or 1-40C organic residues
