5′-dimethoxybiphenyl homologs were reacted with electrophilic perfluorobenzene to yield 7,10-dialkoxy-1,2,3,4-tetrafluoro-6,11-dimethoxytriphenylene (p-TPFn) and 6,11-dialkoxy-1,2,3,4-tetrafluoro-7,10-dimethoxytriphenylene (m-TPFn), respectively. The compounds display hexagonal columnar (Colhex) or lamello-columnar (LamColrec) phase depending on the topology of the aliphatic periphery (i. e. chain-length and symmetry
