Photographs of solutions obtained when the indicated metal salts (10 equiv. from a 100 mmol·L−1 solution in an acetic acid: NH4OAc = 1: 1 aqueous buffer) are mixed with sp3-Tex (0.1 mmol·L−1 in 0.1 mol·L−1 NH4OAc buffer) and heated at 90°C for 10 min (pH ≈ 5‒6). Cations that were found to provide a response were Mn(OAc)2, Co(NO3)3, CoCl3, Cd(NO3)3, InCl3, Hg(OAc)2, Pb(NO3)2, and Bi(OAc)3. The acetic acid: NH4OAc = 1: 1 aqueous buffer was used to convert all cations to their respective acetate derivatives and to control for putative anion effects.
