资源简介：
To realize the molecular design of
new functional silver(I) clusters,
a new synthetic approach has been proposed, by which the weakly coordinating
ligands NO3– in a Ag20 thiolate
cluster precursor can be substituted by carboxylic ligands while keeping
its inner core intact. By rational design, novel atom-precise carboxylic
or amino acid protected 20-core Ag(I)-thiolate clusters have been
demonstrated for the first time. The fluorescence and electrochemical
activity of the postmodified Ag20 clusters can be modulated
by alrestatin or ferrocenecarboxylic acid substitution. More strikingly,
when chiral amino acids were used as postmodified ligands, CD-activity
was observed for the Ag20 clusters, unveiling an efficient
way to obtain atom-precise chiral silver(I) clusters.
