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 monoayer. By this method the result that the twisting and tilting angles of QC10SH moecule in SAM are 50±4° and 24±3°respectively has been obtained.展开更多

The formation of HHQ-metal complexes leads to the appearance of new peaks assigned to the metal ions. The information on stoichimoetry provided by xps indicated that a metal ion is coordinated by two HHQ molecules for La3+ and Cd2+ ions, but by one HHQ molecule for Mn2+ and Ni2+ ions.展开更多
