Abstract:

 A novel quinoline derivative 6-(10-thiol-decaoxy ) quinoline (abbreviated as QC10SH )was synthesized and its self-assembled monoayers (SAMs) were prepared on gold for the first time. Wettability measurement on QC10SH SAM reveals a hydrophilic surface. RA-IR researches suggests that the SAM has formed highly-organized and closely-packed structure. A method is developed for quanitatively evaluating the molecular orientation in monolayer. By this method the result that the twisting and tilting angles of QC10SH molecule in SAM are 50±4° and 24±3°respectively has been obtained.

Key words: Quinoline derivative, Self-assemble monolayer(SAM), Reflectance-absorption infrared(RA-IR) spectroscopy, Molecular orientation
