AbstractOrganic–inorganic hybrid thin films containing [Ti4(μ3-O)(OiPr)5(μ-OiPr)3(O3PPh)3]·THF (TiOPPh) were prepared via the hybridization of TiOPPh with poly(vinyl phenol) (PVP), poly(styrene-co-allyl alcohol) (PSA), and poly(bisphenol A-co-epichlorohydrin) (PBE) using spin coating. These thin films were characterized in terms of their transmittance, pencil hardness, and surface morphologies. The transmittance values of the PVP hybrid thin films decreased with the addition of TiOPPh because of the formation of Ti–O–Ph bonds. The pencil hardness values of the hybrid thin films were in the order PVP > PBE > PSA hybrids. Using confocal laser scanning microscopy and atomic force microscopy, the pencil hardness values were determined to be strongly dependent on the surface morphology, such as the roughness and presence of pin holes. The model cluster was synthesized by the reaction of TiOPPh with excess ethanol to study the structures of the TiOPPh in hybrids. From the nuclear magnetic resonance spectroscopy and single-crystal X-ray structure analyses, the main core structure of the model cluster was found to retain the core structure of TiOPPh.Organic–inorganic hybrid thin films containing [Ti4(μ3-O)(OiPr)5(μ-OiPr)3(O3PPh)3]·THF (TiOPPh) as element blocks were prepared via hybridization with the hydroxyl-substituted organic polymers (PVP, PSA, or PBE) by spin-coating. The hybrid thin films were characterized by AFM, DSC, and pencil hardness. The pencil hardness values of the PVP hybrid thin films were in the order 20 > 40 > 0 wt% and were dependent on the surface smoothness. When TiOPPh was reacted with excess ethanol, the core was retained. Therefore, the core of TiOPPh will be retained in the hybrid polymers.

含膦酸钛团簇的有机-无机杂化薄膜的性质和表面形貌

摘要 通过 TiOPPh 与聚乙烯苯酚 (PVP) 的杂化制备了含有 [Ti4(μ3-O)(OiPr)5(μ-OiPr)3(O3PPh)3]·THF (TiOPPh) 的有机-无机杂化薄膜，使用旋涂的聚（苯乙烯-共-烯丙醇）（PSA）和聚（双酚A-共-表氯醇）（PBE）。这些薄膜的特征在于它们的透射率、铅笔硬度和表面形态。由于 Ti-O-Ph 键的形成，PVP 混合薄膜的透射率值随着 TiOOPPh 的加入而降低。混合薄膜的铅笔硬度值的顺序为 PVP > PBE > PSA 混合材料。使用共聚焦激光扫描显微镜和原子力显微镜，确定铅笔硬度值强烈依赖于表面形态，例如粗糙度和针孔的存在。该模型簇是通过 TiOPPh 与过量乙醇反应合成的，以研究杂化物中 TiOPPh 的结构。从核磁共振波谱和单晶 X 射线结构分析中，发现模型簇的主要核心结构保留了 TiOOPPh 的核心结构。含有 [Ti4(μ3-O)(OiPr) 的有机-无机杂化薄膜)5(μ-OiPr)3(O3PPh)3]·THF (TiOPPh) 作为元素块是通过旋涂与羟基取代的有机聚合物（PVP、PSA 或 PBE）杂交制备的。混合薄膜的特征在于 AFM、DSC 和铅笔硬度。PVP 混合薄膜的铅笔硬度值约为 20 > 40 > 0 wt%，并且取决于表面光滑度。当 TiOPPh 与过量乙醇反应时，核被保留下来。所以，
