Phenothiazine-Based 2D Covalent Organic Framework for Efficient Visible-Light-Induced Free Radical Polymerization
Phenothiazine derivatives have attracted
tremendous research attention
due to their rich redox-active properties. In this work, a phenothiazine-based,
highly crystalline, and two-dimensional covalent organic framework
(PTz-An-COF) was developed. PTz-An-COF exhibited a low bandgap of
1.92 eV with a broad visible-light absorption. Interestingly, PTz-An-COF
can serve as an efficient photoinitiator for visible-light-induced
radical polymerization of methyl acrylate. Remarkably, PTz-An-COF
as a photoinitiator can be easily recycled and maintains the same
catalytic activity as that of pristine PTz-An-COF. This work provides
new insights into the development of high-performance heterogeneous
photocatalysts for radical polymerization
