“…These polymers are blue emitters and exhibit mainly “monomer emission,” which can be due to the fact that the cross‐linked structure of the polymer matrix restrains the mobility of the pyrene units thereby preventing their interaction to form excimers. Very intense excimer emission bands have been observed in other labeled polymers previously reported by us …”

“…FT‐IR spectra of PEGDA and poly(PEGDA) were recorded and the bands correspond to those previously reported by us . In the FT‐IR spectra of the different labeled polymers poly(PEGDA‐ co ‐PyBuAc) (not shown) we can observe a series of bands at 2980, 2870 (CH 2 ), 1720 (CO), 1635 (CC), 1290 (CO ester), 1190, 1107, 1059 (CO ethers) and 857, 710 (CH, out of plane) cm −1 .…”

“…In a previous work, we carried out the thermal frontal polymerization (FP) of di(ethylene glycol) ethyl ether acrylate (DEGEEA) in the presence of the same labeled monomer PyBuAc . Unlike PEGDA, this monomer allowed the incorporation up to 10 wt % of the labeled monomer because it was very soluble in DGEEA.…”

“…The synthesis of 1‐pyrenebutyl acrylate (PyBuAc) has been previously reported by us in the literature . In this case, PyBuOH (2.000 g, 7.289 mmol) was dissolved in freshly distilled THF (50 mL) under argon atmosphere; then TEA (1.500 mL, 10.600 mmol) was added with a syringe to the solution.…”

Frontal polymerization (FP) of poly(ethylene glycol) diacrylate (PEGDA) was carried out using benzoyl peroxide (BPO) as radical initiator. In addition, a pyrene containing monomer, 1-pyrenebutyl acrylate (PyBuAc), was incorporated as a fluorescent probe in order to obtain luminescent materials with different chromophore contents. The resulting polymers were characterized by FT-IR spectroscopy in the solid state and their thermal properties were determined by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Moreover, the optical properties of these materials were studied by absorption and fluorescence spectroscopy. The maximum amount of the incorporated pyrene-containing monomer into the polymer matrix was limited to 1 wt % by the polymerization process. The obtained labeled polymers poly(PEGDA-coPyBuAc) exhibited a broad absorption band at 345 nm. The fluorescence spectra of these polymers exhibited mainly "monomer emission" so that no excimer emission was observed. It is possible to tune the color of the emitted light by varying the pyrene content in the samples.

“…We have investigated the photophysical properties of various polymers and compounds bearing pyrene [36]. Pyrene has been also incorporated into various macromolecules with the aim to develop novel photoactive materials [35,36,41,42,43,44,45,46]. Furthermore, we have designed a Fréchet-type dendron containing an increasing number of pyrene moieties with the generation number.…”

In this feature article, a specific overview of resonance energy transfer (FRET) in dendritic molecules was performed. We focused mainly on constructs bearing peripheral pyrene groups as donor moieties using different acceptor groups, such as porphyrin, fullerene C60, ruthenium-bipyridine complexes, and cyclen-core. We have studied the effect of all the different donor-acceptor pairs in the energy transfer efficiency (FRET). In all cases, high FRET efficiency values were observed.
