“…The Figure 12 present the UV-Vis spectra of the synthesized polymers realized in DMF, these results show the existence of an intense peak at 270 nm attributed for the transition (π → π *), the polymer (H) present a second transition (n → π *) observed at 310nm, this transition was absent in the other polymers because their solubility in DMF was low. Results of UV-Vis spectroscopy are consistent with those found by Samanta et al [19], which proves that synthesized polymers may fall in the category of semiconductors.…”

In order to remove metals (Zn & Mg) located in wastewater, a new series of clickable polystyrene Merrifield grafted with azide and alkynes were synthesized and implicated in this domain. In a first step, we transformed the polystyrene Merrifield into the known Azidomethyl polystyrene, in a second step, a coupling reaction between the Azidomethyl polystyrene and dipropargylamine was realized for the synthesis of a new terminated polystyrene alkyne containing one unit of (1,4)-triazole. To increase the length of the chain grafted on the polystyrene Merrifield, several coupling reactions are applied, the main idea of this work was to increase the number of (1,2,3)-triazole units of this grafted chain. The click chemistry based on the Huygens's reaction catalyzed by copper (I) was used in this synthesis, the new polymers containing (1,4)-disubstituted triazole are tested for the extraction of Mg and Zn located in wastewater. The structure of new obtained polymers was confirmed by infrared spectroscopy (ATR-FTIR), UV-visible spectroscopy and elemental analysis for nitrogen. Differential Thermal Analysis (DTA) and Thermo Gravimetric Analysis (TGA) were used to study crosslinking behavior of these polymers. This study shows a low selectivity of studied polymers for the retention of magnesium, while for the Zinc, the percentage removal was average, it's in the order of 30%.

“…To the best of our knowledge, there is hardly any report to employ fullerenes directly in "click" polymerization to obtain polytriazoles with multiple fullerene units containing thiophenes. Only recently we reported that thiophene-based polytriazoles [13] and polyacetylenes [14] could be synthesized on flat surfaces using a graft through approach on self-assembled monolayer (SAM) [15,16]. However, the studies were focussed on flat surfaces which were distinctly different from curved surfaces like fullerenes.…”

“…Due to the optical transparent nature and the property of high electrical conductance, ITO acts as the most preferable anode in organic electronic equipment and planar heterojunction perovskite solar cell. [ 111–113 ] In a recent review, we discussed methods of immobilization of conjugated and semiconjugated organic small molecules/polymers anchored on functionality decorated surfaces by different surface grafting techniques and their applications are solar cell and biotechnology.

Solar cells based on organometal halide perovskites attract increasing research interest as an excellent source of renewable energy due to their inexpensive process, high power conversion efficiency, and availability of abundant raw material. The basic description, current research targets and status, and future perceptions of perovskite‐based photovoltaics along with the strategies toward the enhancement of both (intrinsic and extrinsic) stabilities of high‐efficiency devices are summarized and analyzed. This review provides the required knowledge for this design by studying various commercialized thin‐film technologies, analyzing large‐scale fabrication methods like physical vapor deposition, chemical vapor deposition, inkjet printing, doctor blading, spray coating, and roll‐to‐roll techniques. Addressing the present threat and opportunities for integrating the new material exploration, devices and large‐scale fabrication is conductive to the successful commercialization of the perovskite solar cells (PVSCs). This article presents the overview of the reports of the latest technological enhancement of cell stability, interfacial modification, replacement of electron and hole transport layers, techniques used for minimizing the lead‐based perovskites toxicity, and large‐scale fabrication. Finally, this provides an emphasis on organometal halide perovskite‐based solid‐state solar cell contacts that are believed to be the key factor for achieving highly stable PVSCs.
