Imidazole and Triazole Coordination Chemistry for Antifouling Coatings

Figure 2

Cu²⁺ EPR spectra in MeCN of (a1) PVM-4, (a2) Im, (a3) Me(1)-Im, (a4) Me(4)-Im, (b1) PVM-44, (b2) PVM-44 half field signal, (c1) PMMA, and (c2) H₂O [38, 47]. The paramagnetic centers, that is, the Cu(II) ions, of PVM-44 are closer together compared to PVM-4 which is reasonable due to the larger fraction of imidazole ligands per polymer chain. To be more precise, the coordination complexes are separated by less than 20 Å (see Figure 2(b2)) which is indicated by the EPR half field signal (see Figure 2(b2)).
