Hypercrosslinked porous polymers (HPPs), known for their high surface area and abundant micropores, effectively adsorb dye molecules and facilitate their degradation under light, making them a highly attractive solution. Herein, we synthesized donor-acceptor (DA) based TPA-TAZ HPP through Friedel−Crafts polymerization of triphenylamine as a donor and 2,4,6-trichloro-1,3,5-triazine (TCT) as an acceptor for adsorption and photo-degradation of Rhodamine B (RhB) and methylene blue (MB). The resulting TPA-TAZ HPP exhibits an impressive surface area of 1823 m<sup>2</sup> g<sup>–1</sup>, significant thermal stabilities (<em>T</em><sub>d5</sub>: 663 °C, <em>T</em><sub>d10</sub>: 674 °C, char yield: 75 wt%), and a small band gap of up to 2.04 eV. The porous framework, abundant adsorption sites, and electronegative characteristics of TPA-TAZ HPP enable it to achieve outstanding adsorption performance. It demonstrated removal efficiencies of nearly 99 % for both RhB and MB within 5 minutes, with remarkable adsorption capacities of up to 951 mg g<sup>–1</sup> for RhB and 858 mg g<sup>–1</sup> for MB at ambient temperature. Additionally, TPA-TAZ HPP exhibited exceptional photocatalytic degradation efficiencies, achieving up to 88 % for RhB and 96 % for MB, with reaction rate constants of 5.78 × 10 <sup>–2</sup> min<sup>–1</sup> and 9.62 × 10<sup>–2</sup> min<sup>–1</sup>, respectively. The superior performance of TPA-TAZ HPP can be attributed to its high surface area, small band gap, and donor-acceptor framework, which collectively facilitate efficient charge transfer, thereby enhancing both adsorption and photocatalytic degradation.

Furthermore, the photothermal de-icing performance indicated that both the small ice particles and the large overlying ice layer were all rapidly melted and slid down under light irradiation. The coating also exhibited a strong self-cleaning ability, with contaminants readily removed by the water. Durability tests confirmed that the coating was resistant to the UV light, friction and multiple freeze-thawing cycles, ensuring long-term functionality.
