This content is a preprint and has not undergone peer review at the time of posting.


Catalyst-free spontaneous polymerization for the synthesis of halogen-rich polysulfonates at room temperature in air with 100% atom economy in high yields was developed. The resulting polymers possess various properties, including post-functionalization, extraordinarily high refractive index, visible photodegradation, photoacid generation, multi-color and 3D fluorescent photopatterning, and practical broad-spectrum antibacterial activity.
