Abstract
Alkaline-earth-metal dihexadecyl phosphate salts were synthesized, and thei r thermal stability was evaluated by thermogravimetry. Their thermotropic l iquid crystal behaviour was investigated by differential scanning calorimet ry, polarizing optical microscopy, dilatometry, and X-ray diffraction. On h eating, the calcium, strontium, and barium salts exhibit columnar liquid cr ystal phases, whereas the less ionic beryllium and magnesium salts melt dir ectly into isotropic liquids.
