A simple structural design principle and band position alignment of conjugated microporous polymers for enhanced photocatalytic efficiency is presented. The valence and conduction band positions of the polymer networks can be fine-tuned by altering the substitution positions on the centered phenyl unit to match the required redox potential of the catalytic reactions under visible light.

Herein, we report a novel trifluoromethanesulfonic acid vapor-assisted solid phase synthetic method to construct nanoporous covalent triazine frameworks with highly ordered hollow interconnected pores under mild reaction conditions.

High surface area porous conjugated polymers were synthesized via the high internal phase emulsion polymerization technique and micropore engineering as efficient heterogeneous photocatalysts for highly selective oxidation of organic sulfides to sulfoxides under visible light.

Covalent triazine frameworks (CTFs) have attracted a great deal of attention as an attractive new class of visible light-active, metal-free, and polymer-based heterogeneous photocatalysts. CTFs have demonstrated promising characteristics such as synthetic diversity, stability, nontoxicity, pure organic nature, and enhanced ordered structure. In this review, we aim to summarize the recent developments in CTFs ranging from novel preparation methods to critical factors that directly impact their photocatalytic efficiency. Various physical and chemical design strategies for morphology, band structure, charge separation, and transfer optimization described in the literature are discussed. Emphasis is placed on the enhancement and maximization of photocatalytic efficiencies of specific applications such as photoredox organosynthesis, water splitting, CO2 photoreduction, H2O2 generation, etc.
