The phase behaviour of metal carboxylates has been the center of significant research over several decades, mainly because they exhibit several pre-melting phases on heating; some of which are liquid crystalline whilst others are crystal-crystal phases. Since for some compounds smectic C type mesomorphic phases are observed, there is great potential for application in Liquid Crystal Display Devices (LCD). Furthermore, their high stability, low toxicity and relative cheapness indicate that they represent viable alternative to conventional nematic and twisted nematic liquid crystals....
