Fluorescence dyes from the pressure cooker
TU Wien
From big molecules to small molecules
Previously, Miriam Unterlass' team had developed a novel process for high-performance polymers, which equally takes place in hot water. The hydrothermal synthesis of perylene bisimide dyes now shows for the first time that small molecules can also be generated "in the pressure cooker". The order of developments is rather untypical. Normally, novel synthetic pathways are first developed for small molecules - which are often easier to conceive - and later transposed to polymers, i.e. "big molecules". Despite their small size, the hydrothermal synthesis was however very challenging. For perylene bisimides. They are very apolar, which means that they do not like water - at room temperature. By heating the water to increased temperatures, this challenge can however be met. The hydrothermal synthesis of perylene bisimides is highly efficient and environmentally friendly.
