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).
Highlights
Is able to maximize encapsulation of the luorophores and allow for processing for the desired end application.[27,28]
Bandyopadhyay et al reported another CMP type in common organic solvents due to their extended crosslinked material this time using a dioctylcyclopentyl monomer, which network structure, which ensures their permanent porosity. could be fabricated as a powder, solution and as nanoparticles. This lack of solubility hinders the processing of the materials with a be tuned toward speciic applications such (BET) surface area of 405 m2 g−1.[30]. Wood and co-workers thereby limiting their potential applications despite their many synthesized the irst soluble hypercrosslinked polymers, syntheinteresting and advantageous properties.[18]
There are many sub- sized by intramolecularly crosslinking individual poly(styrene) classes of Microporous organic polymers (MOPs) including conjugated microporous polymers chains at high dilution with surface areas ranging from 187 to (CMPs)[19,20] and hypercrosslinked polymers (HCPs)[21,22] but 724 m2 g−1.[31]. Though these examples of soluble MOPs were only one subclass combines permanent porosity with solubility— found to be both porous and soluble, their synthesis either polymers of intrinsic microporosity (PIMs).[23,24]
Summary
Is able to maximize encapsulation of the luorophores and allow for processing for the desired end application.[27,28]. The result of this synthesis was a material consisting of a porous core made solution dispersible by the presence of the long hydrophilic outer PEG polymer chains. We report the synthesis of dispersible microporous polymers to produce white light achieved by post-synthetic modiication (PSM) of a DVB and acrylic acid (AA) solution-stable porous dispersion capable of encapsulating the luorescent dye rhodamine B.
