A study on the photoswitching behavior of azobenzene-based polar hockey-stick-shaped liquid crystals (HSLCs) has been presented. Two new series of five phenyl rings based polar HSLCs have been designed and synthesized. Solution state photoisomerization of

Two groups of the formulae, 4-(4′-hexyloxy)phenylazo-2-(and 3)methyl phenyl-4″-substituted benzoates (Ia-e and IIa-e) were prepared and investigated for their mesophase behavior. Each group consists of five derivatives that differ fr

As compared with a commercially available agricultural fungicide hymexazol, some phenyl-azo phenol derivatives (e.g., 4a, 4b, 4f, 4n, 4q, 4u, and 4v) exhibited the more promising and pronounced antifungal activities in vitro against seven phytopathogenic fungi. It seemed that 4-((un)substituted phenylazo)-phenol and 4-((un)substituted phenylazo)-3-methylphenol might be considered as new lead structures for further design of agricultural fungicides.

According to the results of elemental analysis, high-performance liquid chromatography, and NMR, UV, and IR spectroscopy the preparatively isolated products of the reactions of the p-nitrobenzenediazonium ion with p-(phenylazo)phenol and its derivatives are derivatives of 4,4-bis(p-nitrophenylazo)-2,5-cyclohexadien-1-one.The products are stable in the solid state and in neutral media.In acid and alkaline media they are split with the formation of the nitrobenzenediazonium ion and the corresponding p-(phenylazo)phenols.The product with a cyclohexadienone structure is regarded as a model of the second of the two successively formed intermediate complexes in the azo coupling.
