Is it possible to create a new class of materials from very different substances using the "one-pot synthesis" approach? Chemists at the University of Konstanz explain how they enable the synthesis of such novel materials.

People have long dreamt of developing materials to circumvent the challenges of daily life. Ideally, one could capitalize on a combination of the features of different materials, profiting from their advantages while avoiding the disadvantages. In chemistry, this concept has been applied to hybrid materials, particularly with the combination of organic and inorganic compounds.

Organic materials are known for their functional diversity, while inorganic materials offer superior stability. However, the fusion of organic and inorganic substances poses significant challenges due to the differing reaction conditions required for their formation. The research team led by Professor Miriam Unterlass at the University of Konstanz employs a method that balances these contrasting conditions, allowing the reactions to occur simultaneously and synergistically in a single reaction vessel. Chemists have named this method "one-pot synthesis."

The researchers have fine-tuned this method to achieve optimal reaction conditions, akin to cooking a perfect one-pot meal, where each ingredient must be prepared just to the right state. Key to their success is the precise control of pressure, temperature, and time, along with the right selection of available ingredients, or as chemists call them, starting materials.

"The beauty of our approach lies in its simplicity," says Frank Sailer, who played a significant role in one-pot synthesis while pursuing his doctoral thesis. "We avoid toxic catalysts and solvents, using only isopropanol, a common disinfectant, as a solvent. This makes our process both sustainable and environmentally friendly." The resulting materials, named pigment@TiO2 are composed of special colorant molecules, known as organic pigments, and layered titanium dioxide. Are the results of one-pot synthesis truly the best of both worlds? Actually, they are much more than that. Frank Sailer describes it this way: "We don't just want to achieve a sum of all the properties of both individual components but new, synergetic properties that none of the individual materials exhibits." These synergistic properties make pigment@TiO2 materials particularly suitable for battery applications.

Why was this approach not employed to make such hybrid materials in the past? "This is because the idea is very unusual. The organic components are typically not synthesized under the employed reaction conditions," Frank Sailer explains.

Finding such materials and reaction pathways is one of the research goals pursued by Miriam Unterlass' research team. They study how chemical synthesis processes can be optimized to lead to better, more sustainable advanced materials. "We aim to produce better materials faster and in a more environmentally friendly way," says Miriam Unterlass.
