“…24), incorporating p-conjugated diphenylbithiophene and a distyrylbenzene derivative as chromophoric main chain subunits, has been explored as an anion sensor. 42 P41 exhibited visually identifiable colorimetric changes and photoluminescence enhancement in response to fluoride or cyanide versus other common anions in THF. A strong colorimetric change of P41 solutions from pale yellow to orange was observed only in the presence of fluoride or cyanide.…”

“…Step‐growth polymerization of commercial bisphenols and bis(trifluorovinyloxy)biphenyls was shown to afford telechelic and crosslinkable fluorinated arylene vinylene ether (FAVE) polymers (Scheme ). Specifically, these polymers were modularly tailored by functionalization of the aryl group (Ar) for applications including thermally crosslinkable fluoroelastomer additives,7, 8 proton exchange membranes for hydrogen‐based fuel cells,9 polymer light emitting diodes,10 and chemical sensors 11, 12. Bis(trifluorovinyloxy)biphenyls are well known to undergo thermal cyclopolymerization13, 14 to afford an established class of amorphous, processable perfluorocyclobutyl (PFCB) aryl ether polymers for a multitude of high performance materials 15.…”

Fluorinated arylene vinylene ether (FAVE) polymers were prepared from the base-promoted addition of commercial 2,2-bis(4-hydroxyphenyl)hexafluoropropane (6F bisphenol A) to aryl trifluorovinyl ether (TFVE), 2,2 0 -bis(4-trifluorovinyloxybiphenyl)-1,1,1,3,3,3-hexafluoropropane. The step-growth polymerization kinetics by using stoichiometric NaH and catalytic Cs 2 CO 3 were investigated by monitoring the 19 F NMR signals of the aryl TFVEs. The nth order kinetic model was used to determine rate constants over a series of programmed temperatures. Polymerization using stoichiometric NaH resulted in second-order kinetics with an activation energy of 59 kJ/mol. This model kinetic study provided insight into the mechanistic pathways of the FAVE polymer system that has recently shown a lot of interest in many areas of materials science.

“…Among the existing luminescent materials (also known as luminophores), quantum dots (QDs) [ 24 , 25 ], nanoparticles (NPs) [ 26 , 27 ], fluoropolymers [ 28 ], dyes [ 29 , 30 ], and porphyrins [ 31 , 32 , 33 ] have been the most utilized. For the fabrication of sensors, these luminescent materials are usually entrapped or encapsulated in different matrices [ 34 , 35 ] or shells [ 36 , 37 ], which must be designed to facilitate the interaction between the analyte and the sensing material [ 38 ].…”

Luminescence-based sensing applications range from agriculture to biology, including medicine and environmental care, which indicates the importance of this technique as a detection tool. Luminescent optical sensors are required to be highly stable, sensitive, and selective, three crucial features that can be achieved by fabricating them by means of the layer-by-layer nano-assembly technique. This method permits us to tailor the sensors′ properties at the nanometer scale, avoiding luminophore aggregation and, hence, self-quenching, promoting the diffusion of the target analytes, and building a barrier against the undesired molecules. These characteristics give rise to the fabrication of custom-made sensors for each particular application.
