We report here some interesting optical textures and phase behavior exhibited by the binary mixtures of Cholestryl 5-(4-((4-hexylphenylimino) methyl)-3-hydroxyphenoxy) pentanoate (C74) and n-Butyloxybenzylidene- p-pentylaniline (BBPA). The samples with 1% to 30% of BBPA exhibit smectic and cholesteric phases. The intermediate concentrations ranging from 30% to 70% of BBPA exhibit smectic A, smectic C*, smectic G, smectic F and smectic B phases. The mixtures with higher concentrations from 71% to 99% of BBPA show Blue phase - N* - TGBA - TGBC - TGBC* - UTGBC* - Sm A phases, Sequentially. The phase behavior exhibited by the samples of different concentrations of BBPA has been studied using polarizing microscope and from the DSC recordings.
