Premiers Exemples De Sels Heteroaromatiques A Quatre Chaines Paraffiniques Possedant Des Proprietes Mesomorphes Colonnaires

Abstract
Homologous series of diaryl-3,5 dithiolium-1,2 and diaryl-2,6 pyrylium salts, in which aryls possess two flexible alkoxy chains, were synthesized. With n≥8, dithiolium salts exhibit a columnar hexagonal mesophase.
