Multifunctional Imidazole-Based Copper(II) Single Crystal for Sustainable Health and Energy Applications
摘要
A multifunctional copper(II) complex, (1H-imidazole-κN3)[4-methyl-2-({[2-oxido-5-(2-phenyldiazen-1-yl)phenyl]methylidene}amino)pentanoato-κ3O,N,O′]copper(II) (IPMPC), was successfully grown as single crystals using the slow evaporation method in methanol. Its monoclinic structure (space group P21) was confirmed by single-crystal x-ray diffraction with excellent crystalline perfection (HRXRD; FWHM: 13.5 arcsec). Stable polarization switching was observed in the ferroelectric P–E loop (Pr = 0.95 μC/cm2, Ec = 0.9 kV/cm), and magnetic tests showed that the weak antiferromagnetic coupling between Cu(II) centers was predominant. The efficiency of SHG was 1.36× higher than that of KDP. Lattice stability was demonstrated by mechanical testing. IPMPC’s multifunctional optoelectronic and biological potential was highlighted by its powerful antibacterial and anticancer activities, which included suppressing EGFR/PI3K/AKT signaling and exhibiting an IC50 of 37.68 ± 2.17 μg/mL against MCF-7 cells.
