TVP-A, a positively charged photosensitizer with aggregation induced emission characteristics is introduced as a super-efficient, cost-effective, and eco-friendly agent for controlling harmful algal blooms. Due to its positive surface charge, TVP-A has good water solubility and quickly adsorbs onto algal cells floating on the surface of water, triggering algal cell death through oxidative de-struction of the nuclei and chloroplasts of algae. TVP-A is effective at low concentrations and requires sunlight irradiation only for a few minutes to destroy algal blooms, making it applicable for largescale algal bloom control under most weather conditions. The slow self-degradation of TVP-A prevents itsaccumulation and secondary pollution to the environment.
