| Abstract: | 3‐Aminopropyltriethoxylsilane (APS), N‐3‐(Trimethoxylsilyl)propyl]‐ethylenediamine, N‐3‐(Trimethoxylsilyl)propyl]diethyenetriamine were assembled onto silicon surfaces. Using a mixture of acetone and water as solvent, factors which would affect the formation of amino‐terminated self‐assembled monolayers (SAMs), such as water content in solvent and reaction time, were investigated. The structural information of SAMs was collected from contact angle measurements, ellipsometric thickness measurements and X‐ray photoelectronic spectroscopy. Reaction time and water content in solvent produced dominant effects on the formation of amino terminated SAMs. The method introduced in this paper also presents a simple and controllable way to prepare amino‐terminated SAMS.
