The sol-gel process is a green method used in the last few decades to synthesize new organic-inorganic phosphorus-containing hybrid materials. The sol-gel synthesis is a green method because it takes place in mild conditions, mostly by using water or alcohol as solvents, at room temperature. Therefore, the sol-gel method is, among others, a promising route for obtaining metal-phosphonate networks. In addition to phosphorus, the obtained hybrid materials could also contain titanium, zirconium, boron, and other elements, which influence their properties. The sol-gel process has two steps: first, the sol formation, and second, the transition to the gel phase. In other words, the sol-gel process converts the precursors into a colloidal solution (sol), followed by obtaining a network (gel). By using the sol-gel method, different organic moieties could be introduced into an inorganic matrix, resulting in organic-inorganic hybrid structures (sometimes they are also referred as organic-inorganic copolymers).
溶胶 - 凝胶法是过去几十年中用于合成新型有机 - 无机含磷杂化材料的绿色方法。溶胶 - 凝胶合成法是一种绿色方法，因为它在温和条件下进行，主要使用水或醇作为溶剂，且在室温下进行。因此，溶胶 - 凝胶法是获得金属膦酸盐网络等材料的一种有前景的途径。除了磷之外，所得的杂化材料还可能包含钛、锆、硼和其他元素，这些元素会影响其性能。溶胶 - 凝胶过程有两个步骤：首先是溶胶形成，其次是向凝胶相转变。换句话说，溶胶 - 凝胶过程将前驱体转化为胶体溶液（溶胶），随后形成网络（凝胶）。通过使用溶胶 - 凝胶法，可以将不同的有机部分引入无机基质中，从而得到有机 - 无机杂化结构（有时它们也被称为有机 - 无机共聚物）。
