Maximum bonding capacity (saturation condition) was 0.625mg Cu 2+ per mg citric acid, meaning 2mol Cu 2+ per mol citric acid. Complexation tests in the system polyethylenimine–citric acid–copper showed that the polymer is able to complex the copper–citric acid chelate at pH=6 while ...
Therefore, supramolecular systems displaying very high effective molarities are reliably formed in a wide range of experimental conditions and exhibit "all﹐r‐none" phenomena, meaning that the assembly is either fully formed or fully dissociated into the corresponding monomeric components. We summarize ...
