The synthesis and characterization of two sets of triphenylene derived discotic mols. with phenol, aldehyde and acid functional groups was reported. In the first set, triphenylene moiety was tethered with benzene derivatives via an ester linkage, while in the second set via an ether linkage with increased aromatic conjugation. All the mols. have triphenylene disk at one end and with benzene, biphenyl and terphenyl cores at the other end connected via flexible methylene spacers. The chem. structures of the novel compounds were confirmed by IR, NMR spectroscopy and CHN anal. methods. Thermal and liquid crystal texture properties were determined using differential scanning calorimetry, polarized optical microscope and X-ray diffraction studies. Amongst all the novel compounds, only the terphenyl derivative displayed mesomorphism. However, their charge transfer complexes with trinitrofluorenone (TNF) an electron acceptor exhibited columnar mesophases. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2HPLC of Formula: 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
