Salts, mesogenic properties

Metal soaps have long been known to have mesogenic properties. Thus, Vorlander [8 a] in 1910 reported the existence of lamellar phases in the anhydrous salts of alkali carb-... 

It should be noted that SC copolymers based on nonmesogenic SCs and NLO mes-ogenic SCs offer the opportunity to fine-tune the polymer properties by varying the ratio of the NLO mesogenic SCs, although care must be taken to characterize the product, since the final ratios of the SCs may not correspond to the feed concentrations. An interesting example is the series of copolyethers prepared by chemical modification of atactic polyepichlorohydrin with the sodium salt of 4-cyano-4 hydroxybiphenyl [188, 207] (45).
