Red-light Emitting Orthogonally Trireactive Gold Nanoclusters for the Synthesis of Multifunctionalized Nanomaterials.

ABSTRACT: For the development of highly multifunctionalized nanomaterials, the introduction of functional molecules on gold nanoclusters containing thiols preinstalled with connecting groupsconstitutes a promising approach. However, the uniform introduction of multiple connecting groups while avoiding side reactions is a challenging task. Herein, the synthesis of gold nanoclusters (ca. 1 nm) coated with thiol peptides bearing azido, amino, and aminooxy groups is reported. These nanoclusters emit red-light before and after the functionalization, enabling application to cell imaging. A detailed structure analysis using transmission electron microscope and X-ray absorption spectroscopy reveals the formation of Au_n(SR)_m nanoclusters as promising motifs for red-light emission.
