SYNTHESIS,SELF-ASSEMBLING AND REDOX PROPERTIES OF 2-[(omega-SULFANYLALKYL)AMINO]-1,4-NAPHTHOQUINONES

摘要

The newly synthesized 1,4-naphthoquinones linked via nitrogen atom to a short chain with terminal sulfanyl group form self-assembled monolayers on gold.The main electrochemical parameters of the monolayers were determined by cyclic voltammetry.Combined voltammetric and in situ Fourier-transform surface-enhanced Raman spectroscopic studies of the Au electrode modified with the title compounds clearly evidence that naphthoquinone group transforms into naphthalenediol during a reduction process.
