Saddle-shaped tetraphenylenes with peripheral gallic esters displaying columnar mesophases
Tetraphenylenes 2 with eight peripheral gallic esters were prepared in two steps from octamethoxytetraphenylene 1 in 19–72% yield. Investigation of the mesomorphic properties of 2 by DSC, POM and X-ray diffraction revealed that derivatives 2a–d with short alkoxy chain lengths (C(5)–C(8)) did not sho...
