In this paper, novel chiral calamitic compounds, consisting of n-dodecyloxyphenyl substituted pyridine carboxylate core linked to one or two benzene rings through ester linkers was synthesized by multi-step procedures. The other end was varied by introducing a flexible (S)-2-methylbutyloxy or (S)-3,7-dimethyloctyloxy chiral chain. The liquid crystal properties of new compounds were investigated by various exptl. techniques such as DSC, POM and SAXS. The pyridine-based calamitic compounds exhibited enantiotropic chiral smectic mesophases such as SmC*, SmA or uncharacteristic mesophase depending on hetero aromatic rings such as nicotinate or picolinate cores, number of aromatic rings and the type of chiral-branched chain. In the experimental materials used by the author, we found Methyl 5-bromopicolinate(cas: 29682-15-3Reference of Methyl 5-bromopicolinate)
Methyl 5-bromopicolinate(cas: 29682-15-3) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Reference of Methyl 5-bromopicolinate
