A synthetic pathway is described which leads to the formation of pyrro
le with a pendant aromatic groups in the beta-position. Such materials
are found to exhibit a monotropic liquid crystal phase. Beta-substitu
ted pyrroles of this type may be polymerised chemically to form poly(b
eta-substituted pyrroles).
