Efficient and Tunable White‐Light Emission Using a Dispersible Porous Polymer

Abstract

A dispersible porous polymer (PEG113‐b‐DVB800‐co‐AA200) based on the controlled radical polymerization of divinylbenzene and acrylic acid with a poly(ethylene glycol) (PEG) macrochain transfer agent (macro‐CTA) is synthesized and postsynthetically modified with anthracene. This blue‐emitting porous polymer is used to encapsulate the yellow‐emitting fluorophore rhodamine B into its core, resulting in a white‐light emitting dispersion with a quantum yield of 38% and commission internationale de l’éclairage coordinates of (X = 0.33, Y = 0.32).

The order–disorder conundrum: a trade-off between crystalline and amorphous porous organic polymers for task-specific applications

“…196,231 Fluorescent porous materials have been heavily explored for diverse applications ranging from light-emitting devices and light-harvesting to sensors and switches. 226,[232][233][234][235][236][237] The multimodal pores of amorphous POPs were used as the host matrix for the inclusion of a diverse range of guests to achieve tunable emission. [236][237][238] In this context, the development of uorescent amorphous POPs with high porosity and solution processability is signicant owing to their real-time applications.…”

However, the p-conjugated amorphous POPs oen exhibit insolubility due to highly crosslinked structures.…”

Heterogenisation of a carbonylation catalyst on dispersible microporous polymer nanoparticles

“…48 The versatility of these porous materials for encapsulation of molecular species has also recently been demonstrated in the formation of organic white-light emitting dispersions. 49 Here we report the synthesis of a new dispersible porous material by co-polymerisation of 4-vinylpyridine (4VP) with DVB in the presence of a PEG-based macro-CTA. The 4VP functionality allows the material to be post-synthetically modified using iodomethane to generate a cationic support which is used to bind cis-[Rh(CO) 2 I 2 ] − electrostatically.…”
