Nanografting as a pathway to create functionalized two-dimensional inorganic surfaces capable of immobilizing fluorogenic substituted-fluorene dye is demonstrated. Of particular importance is that the self-assembled monolayer of 3-aminopropyltriethoxysilane is successfully modified with 9H-fluorene-9-carbonyl chloride carbonyl chloride via amide coupling reactions. Physico-chemical properties of self-assembled monolayer are studied by water contact angle (WCA) measurements, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The optical properties were determined by photoluminescence spectroscopy. The WCA and AFM data suggest that employing the same functionalization protocol on two different surfaces, (SiO₂/Si) and GaN/Al₂O₃ respectively, may lead to different but meaningful results. XPS results confirm fluorene dye covalently attached onto two-dimensional inorganic surfaces via self-assembled monolayer of aminopropyl silane.

纳米接枝作为创建功能化的二维无机表面的一种途径，能够固定荧光取代芴染料。特别重要的是，通过酰胺偶联反应成功地用9H-芴-9-羰基氯羰基氯修饰了3-氨丙基三乙氧基硅烷的自组装单层。通过水接触角（WCA）测量，原子力显微镜（AFM）和X射线光电子能谱（XPS）研究了自组装单层的理化性质。光学性质通过光致发光光谱法测定。WCA和AFM数据表明，在两个不同的表面（SiO ₂ / Si）和GaN / Al ₂ O上使用相同的功能化协议₃，可能会导致不同但有意义的结果。XPS结果证实芴染料通过氨丙基硅烷的自组装单层共价附着在二维无机表面上。
