Carboxylatochromium complexes

Polynuclear complex salts of chromium, aluminum, iron and cobalt are reported to have been used to form the alignment layers for liquid crystalline materials [2-3]. In Fig. 3.7.2 are the structures of layers on glass surfaces treated by carboxylatochromium complexes of (a) an alkanoic acid and (b) an alkandioic acid. Glass surfaces treated by n-alkanoic acids with more than 3 carbon atoms induce homeotropic liquid crystalline alignment as indicated in Fig. 3.7.2(a). On the other hand. Fig. 3.7.2(b) shows the structure of glass surfaces treated by carboxylatochromium complexes of an alkandioic acid. These surfaces show homogeneous...
