Liquid crystalline properties of 4-methyl-4_-alkoxyazobenzenes (azo-1-n), 4-ethyl-4_- alkoxyazobenzenes (azo-2-n) and 4-propyl-4_-alkoxyazobenzenes (azo-3-n) are described. For these three homologous series, temperatures and enthalpies of phase transitions and the types of mesophases are presented. The influence of the alkoxy chain length on the sequence of mesophases, temperatures of the phase transitions and the entropy effects are discussed.
