Condensation of aromatic and heterocyclic aldehydes with benzenediacetonitriles

Abstract: The values 1437 and 3031 cm.-1 were used twice, for a total of 14 wavenumbers.The first three values in this list (below 600 cm.-1) were taken from Crowder (2), and the remaining values were taken from Moritz (6). The methyl thiocyanate molecule has seven atoms and therefore has 15 fundamental vibrational frequencies. Vapor state infrared frequencies are available for all 15 except for the methyl torsion, for which no experimental value is available, and the symmetric C-S-C stretch, for which the liquid state … Show more

“…In the latter case, an attractive variety of liquid crystalline organizations has been obtained to date. With a focus on classical liquid crystals, nematic[10,12,14d,101] and smectic[10,12,14b,d,101b,g,102] mesophases from typical rod‐like molecules, as well as columnar liquid crystalline organizations with different molecular designs, have been described. Both low molecular weight compounds and macromolecules (homopolymers,[101d,e,102a] homopolymers doped with a CS‐LC,[101o] copolymers, or even H‐bonded supramolecular polymers)[101j,105] have been used with success.…”

On following common liquid crystal molecular design trends, CS[101f,102b] or DCS[10,12,14b,d,101a,n] structures with a reduced number of terminal flexible chains (alkoxy‐ or alkyl‐tails) as lateral substituents or combined with amino,[102c,106] carboxylic acid, or ester groups have allowed the synthesis of rod‐like molecules that form nematic or smectic phases.…”
