Antibacterial activity of polymeric substrate with surface grafted viologen moieties

TGA/DTA–FTIR–MS coupling as analytical tool for confirming inclusion complexes occurrence in supramolecular host–guest architectures

“…The scientific interest of such salts grew due to some specific applications including electron carriers, pro-oxidants for oxidative stress testing, cardiovascular agents, herbicides, neuromuscular and hypotensive agents, molecular wires in electronic devices, electrochromic display devices [1,2]. Viologens also exhibit antibacterial efficiency against some microorganism species [3], such as Escherichia coli, due to their DNA strand scission ability [4]. Michaelis first exploited viologens' electrochemical properties in 1933 [5].…”

Influence of the Hofmeister series of anions on the molecular organization of positively ionized monolayers of a viologen derivative

“…Viologens are electroactive, being stable in at least three different oxidation states, and offer a significant electrochromic response. Viologens have found use in solar energy storage systems, as electron mediators in herbicides, and have been used to fabricate modified electrodes, bioelectronic devices, electrochromic writing paper, and molecular wires [12][13][14][15][16][17][18][19], amongst other applications [20][21][22][23][24]. The properties and consequently applications of viologens are sensitive to a variety of factors, including the nature of anions X − [12].…”

Polycation‐Grafted Poly(vinylidene fluoride) Membrane with Biofouling Resistance

“…In Figs. 2 c and d, an additional peak at 1637 cm -1 is assigned to the combination of C-H and C-N stretch [25]. This result indicates the existence of 4,4 -bipyridine.…”

“…The functional monomer, 4,4 -bipyridine, has attracted considerable interest because of the wide range of applications in electrochromic devices, agriculture, and medicine [23]. It was also tethered on solid surfaces, such as stainless steel (SS), poly(ethylene terephthalate) (PET), and Si, to inhibit microbial adhesion and corrosion [24][25][26]. Liu et al [27] synthesized the copolymer (PVDF-g-VBC) of PVDF grafted with 4-vinylbenzyl chloride (VBC) via thermally induced graft copolymerization.…”
