The structures of the investigated ligands in their fully deprotonated ionic forms. From now on, the compounds in this article will be referred to with the names A1–A3 and B1, omitting the charge for the sake of simplicity. In the literature relating to these compounds, the following acronyms have been used for A1–A3 and B1, respectively: DQ1, DQ716, DQ715 and DT1 (Crisponi et al., 2013). |
