Growth of ethyl 2-cyano 3-(4-(dimethylamino) phenyl) acrylate single crystal and its structural, optical, thermal and electrical characterisations

Ethyl 2-cyano 3-(4-dimethylaminophenyl) acrylate crystals were grown by slow cooling method by the condensation reaction of 4-dimethylaminobenzaldehyde and methyl cyanoacetate. The molecular structure of the crystal was confirmed by single crystal X-ray diffraction, 1H Nuclear Magnetic Resonance (1H NMR), 13C Nuclear Magnetic Resonance (13C NMR) and Mass spectrum. The single crystal X-ray diffraction study revealed that the crystal belongs to the triclinic crystal system with space group P. The functional groups of the crystal were confirmed by Fourier transform infrared spectrum. The absorption properties of the crystal were analysed by Ultraviolet–Visible absorption spectrum. The Molar extinction coefficient of the crystal was also calculated using Beer Lamberts law. The emission behaviour of the compound was analysed by Photoluminescence spectrum. Cyclic voltammetry of the compound was analysed through three electrode system at the scan rate of 100 mV/s and HOMO-LUMO of the crystal was calculated by cyclic voltammetry. The thermal behaviour of the crystal was analysed by Thermal gravimetric and differential thermal analysis (TG-DTA). The photo conductivity of the crystal was measured and the result shows that the crystal exhibits positive conductivity. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
