Two series of compounds resulting from the reaction of alkoxy benzaldehyde with alkoxy amoxicillin were prepared. first series, five compounds were prepared by fixing alkoxy benzaldehyde with carbon atoms (6) with(butaoxy, pentaoxy, hexaoxy, heptaoxy, octakoxy) Amoxicillin, while second series, four compounds were also prepared by fixing alkoxy Amoxicillin with carbon atoms (6) with(butaoxy, pentaoxy, heptaoxy, octakoxy) benzaldehyde, and the necessary measurements were taken to verify the resulting compounds, such as (FTIR), (HNMR), and measurements Regarding the determination of liquid crystalline compounds by polarized light microscopy (POM), it was found that the presence of (nematic and smectic) phases in the case of cooling is in addition to the isotropic phase.
