Cu(II)-based binuclear compound for the application of photosensitive electronic device

Abstract

In this study, an acetylenedicarboxylate based binuclear Cu(II) compound [Cu2(adc)(4-pic)6(H2O)4][ClO4]2 (1) (H2adc = acetylenedicarboxylic acid and 4-pic = 4-Picolene) has been synthesized and well characterized by elemental analysis, infrared (IR) spectra, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD) patterns and single crystal X-ray diffraction (SCXRD) techniques. The binuclear compound undergoes hydrogen bonding interactions to form 1D hydrogen bonded aggregate which further undergoes extensive edge-to-face C-H•••π interactions to make 3D supramolecular motif. The current conductivity of compound 1 was recorded under dark and illuminated conditions. Interestingly, the measured I-V characteristics of the synthesized material under dark and illumination of incident light exhibit a highly non-linear rectifying behavior signifing Schottky diode nature. Furthermore, the enhancement of values of electrical parameter after exposure to illumination of incident radiation indicates the light sensing behaviour of the material. Therefore, the material can be used as a promising candidate in photosensitive electronic device.
