Figure 1: Schematic of synthesizing star polymers via ATRP using a Ti–O cluster initiator. Methyl methacrylate is polymerized with CuBr/PMEDTA in toluene at 65°C. Star-star coupling may also yield dimers as a side product. Figure 2: Photopatterning of metal-oxo cluster (MOC) films via thiol-ene click chemistry. A vinyl-functionalized ZrO₂–MAA is crosslinked with multifunctional thiols under UV/electron beam irradiation, forming a covalently networked thin film on a substrate. Figure 3: Schematic of a Ti–O cluster (TOC)-crosslinked polymer network for solid-state lithium battery electrolytes. PTHF-HDI chains are crosslinked via reactive TOCs, enhancing mechanical integrity and facilitating Li⁺ transport via interactions with LiTFSI.
