This paper examines how stacking modes affect the photocatalytic performance of covalent triazine frameworks (CTFs), revealing that AA stacking enhances hydrogen evolution by 37.4% compared to AB stacking and improves cycling stability.
A new-type of covalent triazine framework derived from 2,5-pyrazinedicarbonitrile as a monomer with a high N/C ratio was designed and synthesized by trimerization at 400 °C with ZnCl2 as a catalyst and salt melt via the ionothermal technique.
A complex Ir(tpy)@CTF, which is synthesized by the coordinative immobilization of [Ir(tpy)Cl3] on a covalent triazine framework, was proven to be a recycle catalyst for the acceptorless dehydrogenative coupling of o-aminobenzyl alcohols with ketones.
In this review, we discuss the progress in the preparation methods and diverse applications for covalent triazine frameworks, hypercrosslinked polymers, covalent organic frameworks, and conjugated microporous polymers.
A novel hypercrosslinked triazine COF photocatalyst (HCTF-2) with excellent photocatalytic performance was constructed by molecular expansion. HCTF-2 has a larger specific surface area and exhibits excellent molecular oxygen activation ability.
