New platform synthesizer revolutionizes material design
Researchers at the Ludwig Maximilian University of Munich have developed the Synthesizer platform, which combines automated chemical synthesis, high-throughput characterization and data-driven modeling in an open system. The tool enables precise control of the growth of nanocrystals and the production of materials with tailor-made optical properties.

Under the direction of Professor Alexander Urban, Synthesizer was developed as part of the e-conversion Cluster of Excellence. For the first time, the modular platform closes the entire chain from synthesis to AI-supported derivation of design rules. The focus is on halide perovskites, whose optical properties such as color, brightness and emission width are crucial for applications in LEDs, solar cells and sensors. Even the smallest differences in the size, shape and structure of the nanocrystals influence light emission.
The platform automates the production of variants, characterizes them optically and lets an AI model learn which parameters lead to desired properties. Synthesizer is flexible, expandable and in principle suitable for other material classes. The LMU team is making the platform freely available and is currently integrating it into the laboratory routine. The results were published in Advanced Materials.
