Organoborane-containing polyacetylene derivatives: synthesis, characterization, and fluoride-sensing properties

Polyacetylenes as Colorimetric and Fluorescent Chemosensor for Anions

“…6). 75 The structure of the spacers between the polymer backbone and boron atom exerted a significant influence on their photophysical response behaviors. For example, with regard to the fluorescence response, the F ¡ addition produced a fluorescence enhancement, fluorescence quenching, and no essential change for 8a, 8b, and 8c, respectively.…”

Chiral, fluorescent microparticles constructed by optically active helical substituted polyacetylene: preparation and enantioselective recognition ability

“…14 For monomers bearing uorescent groups, the resulting polymers are advantageous in terms of the uniform distribution of uorescent moieties. 15 However, there is also a problem in uorescent conjugated polymers, namely, a majority of them, typically exemplied by polyacetylenes, [16][17][18][19][20][21][22] are hydrophobic, which remarkably limits their practical applications particularly in aqueous media. To overcome this problem, conjugated polymer-based particles [23][24][25] (nano-and micro-scaled) being able to be dispersed in water are one of the good choices.…”

Dip in colorimetric fluoride sensing by a chemically engineered polymeric cellulose/bPEI conjugate in the solid state

“…[14][15][16] As sensing oen requires the use of an instrumentation which could monitor the signal produced by the sensor, the possibility of colorimetric sensing by the naked-eye is quite appealing for fast, qualitative and eld-use applications. As far as uoride ion sensing is concerned, the majority of polymeric systems proposed in the literature has been investigated in homogeneous solution, 11,[17][18][19][20][21][22][23][24] while only very few examples of sensors working in heterogeneous phase are known. [25][26][27] Heterogeneous solid sensing systems may warrant an improved chemical stability and recyclability along with low sample contamination, and thus they can lead to important developments in the construction of devices of practical use, especially if coupled with naked-eye recognition ability.…”
