摘要
Engineering the surface of the metal clusters with the core structure maintained and tuning their luminescence in a wide range is still a challenge in the nanomaterial research.We modified six mono-pyridyl ligands with different electronic effects(conjugation effect or induction effect)on a superatomic silver cluster[Ag_(14)(C_(2)B_(10)H_(10)S_(2))_(6)(CH_(3)CN)_(8)](denoted as Ag_(14))through in situ site-specific surface engineering.
