Here you can see an example containing several solvents. The first version of the algorithm will detect MeOH, EtOH, iPrOH and EtOAc in deuterated DMSO. This novel algorithm will be used to automatically detect solvents which appear as impurities in your samples. The synthetic cholesteric liquid crystal polyestereamides described here are similar to new cationic cholesteric liquid crystal polyesters also synthesized in our lab.The assignment module has been greatly enhanced, ranging from new capabilities to transfer assignments from one molecule to another as well as between different spectra (1D and 2D) to new graphical features such as the ability to customize the assignment colors in the molecule and simplified workflow.ġ. Values in the X axis can now be easily and efficiently modified by using the new feature to derive t’ from t and from the i-spectrum index.Ģ. Users will now be able to select concentrations as a parameter in order to create kinetic graphs.Īuto-detection of known solvent impurities Both synthetic polyesteramides have proved to be biocompatible and to act as non-viral vectors in Gene Therapy, transfecting DNA to the nucleus cell. By dip coating technique both polymers self-organize in round nanoclusters about 5 nm thick, observed by AFM, after 3h and 21h grown on Si(100) substrate, deposited in conglomerates about 300 nm, 35 nm high. When dispersed in solution, their helical molecules self-organize on metal and semiconductor surfaces. Morphology of powdered PNOBDME exhibits homogeneous spherical clusters of about 5 m in diameter homogeneously dispersed. Optical rotatory dispersion (ORD) is evaluated.

Thermal behavior of the new compounds is studied by TG and DSC analysis. The two 1 H independent sets of signals observed for each enantiomer is attributed to two diastereomeric conformers: gg and gt, of the torsion containing the asymmetric carbon atom in the spacer. Molecular models show helical polymeric chains with stereo regular head-tail, isotactic structure, explained as due to the higher reactivity of the primary hydroxyl with respect to the secondary one in the glycol through the polycondensation reaction. Two new multifunctional polyesteramides designed as PNOBDME (C34H38N2O6)n: poly and PNOBEE (C26H22N2O6)n: poly, are synthesized as cholesteric liquid crystal, characterized by 1 H and 13 C-NMR, COSY and HSQC and compared to precursor polyesters.
