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.

Formula: C10H16O4. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, is researched, Molecular C10H16O4, CAS is 560-09-8, about Synthesis, characterisation and biological activity of chiral platinum(II) complexes. Author is Jaramillo, David; Buck, Damian P.; Collins, J. Grant; Fenton, Ronald R.; Stootman, Frank H.; Wheate, Nial J.; Aldrich-Wright, Janice R..

Four Pt(II) complexes of 1,10-phenanthroline (phen) and 3,4,7,8-tetramethyl-1,10-phenanthroline (3,4,7,8-Me4phen), with the chiral ancillary ligands (1R,3S)- and (1S,3R)-1,3-diamino-1,2,2-trimethylcyclopentane (R,S-tmcp and S,R-tmcp, resp.) were synthesized and their biol. activity quantified using an in vitro cytotoxicity assay against the L1210 murine leukemia cell line. [Pt(R,S-tmcp)(3,4,7,8-Me4phen)]Cl2 and [Pt(S,R-tmcp)(3,4,7,8-Me4phen)]Cl2 showed an increase in biol. activity over their nonmethylated complexes, [Pt(R,S-tmcp)(phen)]Cl2 and [Pt(S,R-tmcp)(phen)]Cl2. Some chiral discrimination was observed in the in vitro cytotoxicity experiments with the complexes having (S,R) configuration showing higher biol. activity in L1210 cells. Titrations of the metal complexes into ct-DNA and observation of the changes induced in the CD spectra were used to determine the binding constants The binding of these metal complexes to the hexamer d(GTCGAC)2 was studied using two-dimensional 1H NMR spectroscopy. The addition of metal complexes to the hexamer produced upfield shifts of the metal complex of selected resonances, characteristic of intercalation for [Pt(tmcp)(phen)]Cl2, whereas the [Pt(tmcp)(3,4,7,8-Me4phen)]Cl2 complexes only partially intercalate and in a side-on fashion. Through the observation of NOE cross-peaks, two-dimensional NMR experiments provided some insight into the site and groove preferences of these complexes when binding to DNA. Here, the authors report the biol. activity of Pt(II) complexes containing an intercalator and a chiral diamine, which influences the degree to which the complexes can interact with DNA.

HPLC of Formula: 560-09-8. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms.

Author is Chen, Shu-Mei; Chang, Li-Mei; Yang, Xue-Kang; Luo, Ting; Xu, Hai; Gu, Zhi-Gang; Zhang, Jian.

Development of chiral metal-organic frameworks (MOFs) for circularly polarized luminescence (CPL) is a challenging but important task. An example of azapyrene-based chiral MOF thin films [Zn2Cam2DAP]n grown on functionalized substrates (named SURchirMOF-4) for CPL property is reported. By using a liquid-phase epitaxial layer-by-layer method, the resulted SURchirMOF-4 was constructed from chiral camphoric acid and 2,7-diazapyrene ligand, which has high orientation and homogeneity. The CD, CPL, and enantioselective adsorption results show that SURchirMOF-4 has strong chirality and CPL property as well as good enantioselective adsorption toward enantiomers of Me-lactate. The synthesis of azapyrene-based chiral MOF thin films not only represents an ideal model for studying the enantioselective adsorption, but also will be a valuable approach for development of the chiral thin film exhibiting CPL property.

Homochiral metal-organic frameworks (MOFs) are an important class of chiral solids with potential applications in chiral recognition; however, relatively few are available. Of great importance is the availability of low-cost, racemization-resistant, and versatile enantiopure building blocks. Among chiral building blocks, D-camphoric acid is highly prolific, yet, its trans-isomer, L-isocamphoric acid, has remained unknown in the entire field of solid-state materials. Its rich yet totally untapped synthetic and structural chem. has now been studied through the synthesis of a large family of homochiral metal isocamphorates. The 1st observation of diastereoisomerism in isostructural MOFs is presented. Isocamphorate has a powerful ability to create framework topologies unexpected from common inorganic building blocks, and isocamphoric acid should allow access to hundreds of new homochiral materials.
