Abstract

By reacting monohydroxytriphenylene 2 with 1,6-dibromohexane and then condensating with 4- hydroxybenzaldehyde, triphenylene derivative with mono-aldehyde group 4 was prepared in ideal yield. Further treating compound 4 with C60 and sarcosine, the novel discotic C60-triphenylene derivative 5 was prepared by 1,3-dipolar cycloaddition in a yield of 35%. DSC analysis and observation with polarized optical microscopy indicated that compound 5 possessed mesomorphic property.
