讲座简介

The recent years have witnessed the fast grow of fluorogens with aggregation-induced emission characteristics (AIEgens) in biomedical research. The weak emission of AIEgens as molecular species and their bright luminescence as nanoscopic aggregates distinguish them from conventional organic luminophores and inorganic nanoparticles, making them wonderful candidates for many high-tech applications. In this talk, we report our recent discovery of AIEgens exhibiting high brightness and efficient reactive oxygen species generation in the aggregate state and further demonstrate their potential in image-guided cancer surgery and therapy. By integrating accurate material performance predictions from first-principles calculations with Bayesian optimization-based active learning, we developed a self-improving discovery system for high-performance photosensitizers, significantly accelerating materials innovation in biomedical research.
