“…Recently, several copolymeric DO sensors have been exploited with using covalently immobilizable DO responsive chromophores . On the basis of the high gas‐permeability of fluorinated polymers, we reported a NIR luminescent copolymer P(Pt‐TPP‐TFEMA) containing fluoro‐substituted unit as DO sensor film, especially for high‐throughput microbioreactors (Scheme ). It was specifically synthesized from the copolymerization of a platinum complex of 5,10,15,20‐tetraphenylporphyrin (TPP) with trifluoroethyl methacrylate (TFEMA).…”

in Wiley Online Library (wileyonlinelibrary.com) Microbioreactors with multioptical sensors have become increasingly important because of their small working volumes, high degree of parallelization and the available robotics. A novel hydrophobic luminescent copolymer P(Pt-TPP-TFEMA) along with reference P(Pt-TPP-EMA) containing the pendant group of 5,10,15,20-tetraphenylporphyrin (TPP) moiety as low-cost dissolved oxygen (DO) chemosensor film for high-throughput microbioreactors is designed. Its sensor film exhibits fast response to DO with good stability and fatigue resistance, being capable of applying as a low-cost DO indicator for high-throughput bioprocess measurement. Results show that the quenching response of DO increases with the enhancement in the copolymeric hydrophobicity using the presented hybrid fluorinated ethyl methacrylate. Furthermore, the long emission band at 650 nm of chromophore TPP with large Stoke's shift about 250 nm brings several advantages, such as low scattering, deep penetration, and minimal interferences of absorption and fluorescence from the fermentation system, which shows high-promising application in bioprocess monitoring.

“…PMA containing various pendant groups such as n-alkyl (2), isoalkyl (2), cycloaliphatic (2), aryl (2), hydroxyalkyl (3), N,N-disubstituted aminoalkyl (4) and fluoroalkyl (5,6) have been well documented in the literature. By changing the pendant group of PMA, the polarity can be tuned within almost the entire polarity spectrum from hydrophilic to hydrophobic.…”

“…Similarly, PMA having heterocyclic group as pendant such as poly(tetrahydrofurfuryl methacrylate) and amine as pendant group as in poly(dimethylaminoethyl methacrylate) shows hydrophilicity of 30 and 20%, respectively (3,7). But, fluorinated pendant groups like hexafluorobutyl and fluorodecyl made PMA as super hydrophobic and improved the properties such as water and oil repellency, chemical resistance and thermal stability (5,6).…”

Isopropyl and isobutyl lactates were reacted with methacrylic acid to obtain corresponding methacrylates through the azeotropic distillation method and their formation was confirmed by mass spectroscopy. Homopolymers were prepared by the solution polymerization method. Both monomers and homopolymers were characterized by FT-IR and NMR spectroscopic techniques. Hydrophilicity of polymers followed the Fickian process and moisture absorption was in the range of 10-24% (w/w). Glass transition temperature decreased with an increase in isoalkyl chain length of polymers. Thermal stability of polymers was explained on the basis of average molecular interchain spacing value, which was calculated using 2u value of amorphous halo of polymers.

“…Controlled radical polymerization (CRP) can serve as a powerful synthetic tool in the production of well-defined fluorinated polymers with various architectures having predetermined chain lengths and low polydispersities. Fluorinated block copolymers have been synthesized previously via CRPs, involving nitroxide mediated radical polymerization (NMP) [11,12], reversible addition fragmentation chain transfer polymerization (RAFT) [13,14], and atom transfer radical polymerization (ATRP) [15][16][17][18][19].…”

Synthesis of fluorinated amphiphilic block copolymers via atom transfer radical polymerization (ATRP) and Cu(I) catalyzed Huisgen 1,3-dipolar cycloaddition (CuAAC) was demonstrated. First, a PEGMA and MMA based block copolymer carrying multiple side-chain acetylene moieties on the hydrophobic segment for postfunctionalization was carried out. This involves the synthesis of a series of P(HEMA-co-MMA) random copolymers to be employed as macroinitiators in the controlled synthesis of P(HEMA-co-MMA)-block-PPEGMA block copolymers by using ATRP, followed by a modification step on the hydroxyl side groups of HEMA via Steglich esterification to afford propargyl side-functional polymer, alkyne-P(HEMA-co-MMA)-block-PPEGMA. Finally, click coupling between side-chain acetylene functionalities and 2,3,4,5,6-pentafluorobenzyl azide yielded fluorinated amphiphilic block copolymers. The obtained polymers were structurally characterized by 1 H-NMR, 19 F-NMR, FT-IR, and GPC. Their thermal characterizations were performed using DSC and TGA.
