Metallosupramolecular polymers formed with silver(I) ions in aqueous solution

초록

We report supramolecular polymers of a terpyridine-based ligand with an alanine moiety (L) at three different concentrations of AgNO3 (0, 0.5, and 1.0 equiv.) in a mixture of H2O and dimethyl sulfoxide (DMSO) (1 : 1 v/v). The self-assembled L obtained without AgNO3 shows a positive circular dichroism (CD) signal indicating right-handed (P-helicity) helicity. In contrast, the self-assembled L formed in the presence of 0.5 and 1.0 equiv. of AgNO3 shows a negative CD signal indicating left-handed (M-helicity) helicity.
