Interstaple Dithiol Cross-Linking in Au25(SR)18 Nanomolecules: A Combined Mass Spectrometric and Computational Study

A systematic study of cross-linking chemistry of the Au25(SR)18 nanomolecule by dithiols of varying chain length, HS–(CH2)n–SH where n = 2, 3, 4, 5, and 6, is presented here. Monothiolated Au25 has six [RSAuSRAuSR] staple motifs on its surface, and …
