Product Details of 693-67-4. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Coumarin substituted symmetric diaminopyridine molecules: Synthesis, mesomorphic characterizations and DFT studies. Author is Mohammad, AbdulKarim-Talaq; Al-Mohammed, Mohammad Hameed; Srinivasa, H. T.; Ameen, Wissam Ahmed.
Synthesis and characterization of 2,6-diaminopyridine bearing sym. substituted coumarins I [R = n-pentyl, n-octyl, n-nonanyl, etc.] from a lateral side of the mols. was reported. All the mols. I were characterized by standard spectroscopic methods such as IR spectroscopy and NMR spectroscopy techniques. Mesomorphic properties were evaluated by the differential scanning calorimetry and the polarized optical microscope. The measurements showed that the lower members did not favor liquid crystal formation, while higher members were exhibiting liquid crystalline, namely nematic mesophase. The DFT computations manifest the nature of liquid crystal geometrical aspects.
