Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, is researched, Molecular C10H16O4, CAS is 560-09-8, about Investigation on two homologus series of ferroelectric hydrogen bond liquid crystals derived from camphoric acid and alkyloxy/alkyl benzoic acids.Synthetic Route of C10H16O4.
Two ferroelec. series comprising of 12 mesogens are investigated. In the first homologous series, Camphoric acid abbreviated as CA which is a ferroelec. ingredient, formed hydrogen bonds with benzoic acids with oxygen atom abbreviated as nBAO. The carbon chain of the benzoic acids varied from 5 to 12 atoms. Thus eight homologous members are synthesized. This mesogenic homologous series is represented as CA+nBAO. Similarly, Camphoric acid formed hydrogen bonds with alkyl benzoic acids abbreviated as nBA. The carbon number of the benzoic acids varied from 5 to 8. This mesogenic homologous series is represented as CA+nBA. Phases observed includes a new phase variant Smectic X*, and conventional phases C*, I* and G*. DSC thermograms exposed the Tc and corresponding ΔH magnitudes. Dielec. relaxations in smectic C* are discussed for a selected mesogen. The existence of oxygen in CA+nBAO facilitated presence of abundance poly phase morphism.
