The synthesis and measurement of physical properties using DSC, X-ray and optical methods are described for the 2,5-di-(4-alkyloxyphenyl)thiazolo|5,4-d|thiazoles with the alkoxy chains varying from 3 to 8 carbon atoms. The phases observed were principally nematic and smectic C phases but for seven and eight carbons the appearance of a highly ordered smectic phase was observed.
