Antimicrobial Hexaaquacopper(II) Complexes with Novel Polyiodide Chains

Abstract: The non-toxic inorganic antimicrobial agents iodine (I2) and copper (Cu) are interesting alternatives for biocidal applications. Iodine is broad-spectrum antimicrobial agent but its use is overshadowed by compound instability, uncontrolled iodine release and short-term effectiveness. These disadvantages can be reduced by forming complex-stabilized, polymeric polyiodides. In a facile, in-vitro synthesis we prepared the copper-pentaiodide complex [Cu(H2O)6(12-crown-4)5]I6 ´ 2I2, investigated its structure and an… Show more

“…This results in the formation of PVP-I3 − complexes within the biohybrid: The two biohybrids AV-PVP-Sage and AV-PVP-Sage-I 2 absorb in the range between 200 to 450 nm (Figure 3). The iodinated formulation is dominated by absorption peaks of smart triiodides at 291 and 359 nm in compliance with our previous investigations (Figure 3a,b) [31,56,[59][60][61][62][63]72].…”

“…The very weak absorbance by iodine moieties in the UV-vis spectroscopic analysis confirms the same results (Figure 5, Table 2). Pentaiodide units are not available in our title compound because they usually appear around 137 to 147 cm −1 and 167 cm −1 [59,78,79]. Free iodine absorbs usually at 172 cm −1 , but is not available in free form in our biohybrid AV-PVP-Sage-I 2 (Figure 5, Table 2) [53,59,80,81].…”
