“…The highest activity was achieved in the terpolymerization of VCHO/CO 2 /PA, with an impressive epoxide conversion of 93 % and a TOF value of 39 h À 1 . The formation of polyester segments for all the investigated monomers obtained from catalytic systems of 1-2/PPNCl was confirmed by 1 13 C signals of the carbonyl groups at 169-170 ppm). [52] It is also worth noting that the anhydride conversion into the corresponding polyester segments was higher than 99 % in all cases, as confirmed by the absence of signals related to unreacted SA (at 2.89 ppm), DGA (at 4.30 ppm) or PA (at 8.04 and 7.63 ppm) in 1 H NMR spectra of crude polymers (entries 1-8, and 11-14,Table 1).…”

“…In order to get insights on the synthesis of polyester and polycarbonate segments, the terpolymerizations of CHO, CO 2 and DGA, catalyzed by 1 or 2 in combination with PPNCl, were monitored by 1 H NMR spectroscopy during the initial 5 h, and 3 h of reaction respectively. Aliquots of the reaction media were taken after 30 min of reaction and subsequently after intervals of 1 h for overall 5 h and analyzed by NMR.…”

The ternary copolymerization of a series of cyclic anhydrides with epoxides and carbon dioxide using dinuclear [OSSO]‐type chromium (III),1, and ‐iron(III), 2, complexes (0.1 mol%) in combination with (bis(triphenylphosphine)iminium chloride) (PPNCl, 0.5‐1.0 mol with respect to catalyst) as co‐catalyst is reported in this study. The results have yielded copolymers with polyester and polycarbonate segments with high molecular weights and narrow dispersity. The catalytic systems 1‐2/PPNCl were tested in the copolymerization of different epoxides, such as propylene oxide (PO), cyclohexene oxide (CHO), and vinylcyclohexene oxide (VCHO), with a variety of cyclic anhydrides, such as phthalic (PA), diglycolic (DGA) and succinic (SA), with CO2 pressure of 20 bar, temperature range of 45‐80 °C in 24 h. Anhydride reaction, affording the polyester segments, exceeded the conversion of 99% in all the explored cases. On the other hand, in the case of epoxide copolymerization with CO2, for the propylene oxide (PO) reaction, the selectivity towards polypropylene carbonate (PPC) without polyether linkage consistently was >99%. For the terpolymerization of PO, CO2 and diglycolic anhydride (DGA), a notable epoxide conversion of 86%, selectively to polycarbonate, with TOF value as high as 36 h‐1, was achieved.

The accessibility to clean water is essential for humans, yet nearly 250 million people die yearly due to contamination by cholera, dysentery, arsenicosis, hepatitis A, polio, typhoid fever, schistosomiasis, malaria, and lead poisoning, according to the World Health Organization. Therefore, advanced materials and techniques are needed to remove contaminants. Here, we review nanohybrids combining conducting polymers and zinc oxide for the photocatalytic purification of waters, with focus on in situ polymerization, template synthesis, sol–gel method, and mixing of semiconductors. Advantages include less corrosion of zinc oxide, less charge recombination and more visible light absorption, up to 53%.

The molecular engineering of conjugated systems has proven to be an effective method for understanding structure–property relationships toward the advancement of optoelectronic properties and biosensing characteristics. Herein, a series of three thieno[3,4-c]pyrrole-4,6-dione (TPD)-based conjugated monomers, modified with electron-rich selenophene, 3,4-ethylenedioxythiophene (EDOT), or both building blocks (Se-TPD, EDOT-TPD, and EDOT-Se-TPD), were synthesized using Stille cross-coupling and electrochemically polymerized, and their electrochromic properties and applications in a glucose biosensing platform were explored. The influence of structural modification on electrochemical, electronic, optical, and biosensing properties was systematically investigated. The results showed that the cyclic voltammograms of EDOT-containing materials displayed a high charge capacity over a wide range of scan rates representing a quick charge propagation, making them appropriate materials for high-performance supercapacitor devices. UV-Vis studies revealed that EDOT-based materials presented wide-range absorptions, and thus low optical band gaps. These two EDOT-modified materials also exhibited superior optical contrasts and fast switching times, and further displayed multi-color properties in their neutral and fully oxidized states, enabling them to be promising materials for constructing advanced electrochromic devices. In the context of biosensing applications, a selenophene-containing polymer showed markedly lower performance, specifically in signal intensity and stability, which was attributed to the improper localization of biomolecules on the polymer surface. Overall, we demonstrated that relatively small changes in the structure had a significant impact on both optoelectronic and biosensing properties for TPD-based donor–acceptor polymers.
