UV-induced room temperature synthesis of microporous ladder polymers with efficient photosensitization

Deeper Insight into Photopolymerization: The Synergy of Time-Resolved Nonuniform Sampling and Diffusion NMR

“…The synthesis of H2banthbn was carried out according to the literature protocols with some modifications. , Antraldehyde (1 g, 4.85 mmol) was dissolved in fresh distilled tetrahydrofuran (THF)/methanol (v/v = 30 mL/20 mL) mixed solvents under an inert atmosphere. Butane-1,4-diamine (213 mg, 2.42 mmol) in 10 mL of methanol was added dropwise.…”

Recent advances on anthracene-based photoinitiators of polymerization

“…By using anthracene as the monomer, synthesis of microporous ladder polymers by photodimerization was beneficial for the design of porous structures usable for advanced separation and catalysis. [244] If anthracene was used in the past as a monomer and as a UV photosensitizer for cationic and free radical polymerizations, dyes absorbing in the visible range were also elaborated with this scaffold, enabling to develop approximately ten different families of visible light photoinitiators. In this review, an overview of the recent advances concerning the design of visible light photoinitiators of polymerization is provided.…”

Polymer Synthesis Based on Self‐Accelerating 1,3‐Dipolar Cycloaddition Click Reactions†

“…Since the concept of click chemistry was introduced by Sharpless and coworkers in 2001, [ 18 ] it has played a significant role in polymer chemistry and materials, due to its high efficiency, orthogonality, and versatility. [ 19‐21 ] Although a variety of click reactions such as copper(I) catalytic cycloaddition of azide with alkyne (CuAAC), [ 22‐24 ] thiol‐ene, [ 25‐26 ] Diels‐Alder [ 27‐29 ] and amine‐active ester [ 30‐31 ] reactions have been found their roles in constructing polymer materials, the self‐accelerating click reactions were seldomly reported and applied in polymer research fields. By elaborately designing the molecular structure of bis‐azide compounds, CuAAC has been endowed with the self‐accelerating property.…”
