Abstract

Cationic self-assembled monolayers (SAMs) composed of quaternary ammonium (QA) sulfur derivatives have been synthesized to control the distance between charged headgroups on gold substrates. Two molecules bearing resembling molecular structures,“gemini”-structured didodecyl dithiol (HS-gQA-SH) and didodecyl disulfide (QA- SS-QA), were utilized in this study, and the formation and structure of the SAMs were ...
