Identification of thiol from 11-(9-carbazolyl)-1-undecyl disulfide by NMR spectroscopy and single step coating of gold nanoparticles

摘要

Disulfide-functionalized fluorescent derivative of carbozole named 11-(9-carbazolyl)-1-undecyl disulfide (CBZDS) has been synthesized. Proton nuclear magnetic resonance spectroscopy was used to distinguish thiol from its corresponding symmetrical disulfide. Single step synthesis of gold nanoparticles coated with CBZDS was carried out which resulted in stable monolayers of CBZDS on gold nanoparticles.
