“…Yield: 47%. 1 3-Methyl-4-(tetraethoxy) thiophene (2) was synthesized using a similar procedure as that described for the previous compound [33]. Tetra(ethylene glycol) (13.74 g, 70.75 mmol) and Na (1.71 g, 27.8 mmol) were reacted at 80 C for 4 h under nitrogen atmosphere to give the corresponding alkoxide.…”

“…In this context, polythiophene (PT) and thiophenes copolymers are interesting materials that can be used in many areas, such as electrical conductors, light emitting diodes (LEDs), transistors, sensors, batteries, solar cells, and others . Moreover, thiophene copolymers are versatile as they can emit in distinct wavelength (300–500 nm) .…”

The use of blends can be a strategy to obtain new properties or to optimize already existing properties in one of the polymers. In luminescent blends, the presence of a non‐conjugated polymer can maximize its emitting properties. However, the parameters to form this blend are fundamental to obtain homogeneous, translucent and good emission films. The present work analyzed parameters such as solution concentration, solvent, and amount of conjugated polymer, drying time, and drying temperature in order to obtain a luminescent blend. The results showed that these parameters are important in the absorption and emission of the materials, and as little as 5 wt% of the conjugated polymer in the blend allows obtaining an emitting blend with few aggregates.

“…The chromic properties of substituted polythiophenes make them excellent prospects for light emitting diodes [18], gas sensors [19,20,21], biomedical applications [22], metal ions sensors [23,24], biosensors [25,26,27,28], and other related applications [29,30,31].…”

“…We studied the effect of the internal stacking of the pyrene groups on the optical and photophysical properties [33,34,35,36,37]. Very recently, we carried out the incorporation of pyrene moieties into polythiophenes in order to obtain donor-acceptor systems for optical applications [29,30,31,38,39]. These polymers can be synthesized either by chemical or electrochemical methods.…”

A novel series of pyrene containing thiophene monomers TPM1-5 were synthesized and fully characterized by FTIR, MS, 1 H-and 13 C-NMR spectroscopy; their thermal properties were determined by TGA and DSC. These monomers were chemically polymerized using FeCl 3 as oxidizing agent to give the corresponding oligomers TPO1-5) and they were electrochemically polymerized to obtain the corresponding polymer films deposited onto ITO. All oligomers exhibited good thermal stability, with T 10 values between 255 and 299˝C, and T g values varying from 36 to 39˝C. The monomers showed an absorption band at 345 nm due to the S 0 Ñ S 2 transition of the pyrene group, whereas the fluorescence spectra showed a broad emission band arising from the "monomer" emission at 375-420 nm. The obtained polymers exhibited two absorption bands at 244 and 354 nm, due to the polythiophene and the pyrene moieties, respectively. The fluorescence spectra of polymers showed a broad "monomer" emission at 380-420 nm followed by an intense excimer emission band at 570 nm, due to the presence of intramolecular pyrene-pyrene interactions in these compounds.
