“…1209 Polychloroprene degradation by photo-Fenton was analyzed by FTIR, 13C NMR, DSC, and conductivity measurements. 1221 The formation of carbonyl on degraded polychloroprene by-product was confirmed by the presence a signal at 203.5 ppm on 13 C NMR. 1221 The durability of a silica-filled chloroprene rubber used for offshore applications was studied by accelerated aging and long-term exposure to marine environment.…”

“…In material science, multifunctional metal complexes having magnetomolecular properties are of interest because they found potential applications in the field of sensors and biology (Chelebaeva et al, 2009 ; Montgomery et al, 2009 ; Yuan et al, 2018 ). In recent literatures, different groups have reported the syntheses of different bimetallic complexes with bifunctional magnetomaterial properties (Freitas et al, 2010 ; Kumar et al, 2019 ; Wu et al, 2019 ). Here, the magnetic properties of single molecules are of interest, and significant amount of results is available (Sessoli et al, 1993 ; Gatteschi and Sessoli, 2003 ; Tasiopoulos et al, 2004 ; Bogani and Wernsdorfer, 2010 ; Van Slageren, 2011 ; Vincent et al, 2012 ; Wu et al, 2019 ).…”

Schiff base ligand N,N′-bis( o -vanillinidene) ethylenediamine ( o -VEDH 2 ) has been employed to synthesize new [Co II Co IV ( o -VED)(OAc) 2 (μ 2 -OAc)(OMe)]•MeOH ( 1 ) and [ ( o -VED) 2 (en) 2 (NCCH 3 )(OCH 3 )][La(NO 3 ) 6 ]( )•2MeOH•MeCN•H 2 O ( 2 ) metal–organic frameworks (MOFs) that have interesting single molecule magnets (SMMs) property. The synthesized complexes are characterized by single crystal X-ray diffraction, fourier transform infrared spectroscopy (FTIR), UV-visible spectroscopy, and squid magnetic measurement. Single crystal X-ray data show that both complexes crystallize in the monoclinic crystal system with P 2 1 / c (14) and P 2 1 / n (14) space groups and generate unique MOF-like structures. Overall, both the metal centers of 1 form octahedral geometry with a butterfly core structure. Variable temperature ( T ) and field ( H ) solid-state direct-current (dc) and alternative current (ac) magnetic susceptibility measurements were performed on both the complexes over 1.8 to 300 K, which exhibited a ground state spins (S) of 4 and 5 of complexes 1 and 2 , respectively. The AC out-phase and in-phase properties of complexes show SMMs. Other properties such as optical, sensing, and DNA-binding interactions were also investigated by the complexes. Complexes 1 and 2 have energy band gaps of 3.7 and 3.03 eV indicating semiconductor properties. Simultaneously, complex 1 was found to sense H 2 O 2 with a rate constant ( k ) = 1.59 × 10 −4 s −1 , whereas complex 2 was found to bind with calf-thymus–DNA by intercalation mode with binding constant ( K b ) of 1.22 × 10 5 M −1 .
