Chemically-induced discotic liquid crystals. Structural, studies with NMR spectroscopy

The use of nuclear magnetic resonance (NMR) spectrometry for the structural studies of chemically-induced discotic liquid crystals was discussed. The synthesis of the phase inductor with two deutrons in the phenyl ring was accomplished in a single step using the catalytic exchange procedure. The reaction was quenched by the addition of 5 ml D2O, the organic layer was left to evaporate and 0.38 g of the product was obtained. The degree of deuteriation was found by proton NMR to be approximately 70%.
