“…Dipolar chromophores have been extensively studied due to their wide range of applications in diverse fields such as in OLED devices,, organic photovoltaic cells, and non‐linear optics . These particular chromophores are push–pull conjugated molecules consisting of electron donor (D) and electron acceptor (A) groups connected through a conjugated π‐bridge.…”

We report the synthetic routes to mono‐ and di‐TCBD adducts onto N‐(het)arylpyrrole derivatives. We present herein two series of panchromatic chromophores bearing different combinations of donor–acceptor moieties. Additionally, we observe an impact of the nature of the central core. Cyclic voltammograms show very different behaviors at negative potentials between the two series. Particularly, four waves are observed for symmetrical di‐TCDB adducts, thus indicating a communication through the central unit despite the non‐planarity of these molecules.

“…Hence, there would be undergone an intramolecular charge transfer from the donor to the acceptor upon excitation by light and could result in a photo-emitting light. 21,29,30 In addition, the fluorescence intensity of Py-N-PBIS decreased gradually with the increase of Co 2+ content (Figure 7(d) to (f)). It is inferred that the “push-pull” π-electron mode was destroyed after Py-N-PBIS coordinated to the Co 2+ metal ion, resulting in decreasing of fluorescence intensity and fluorescence quenching.…”

N-substituted metal-coordinated cross-linking polybenzimidazole pyridine sulfone, as novel class of high-performance functional polymers, has been obtained by the coordination of N-substituted polybenzimidazole pyridine sulfone (Py-N-PBIS) ligand with varying content of metallic ion (Co2+, Ni2+, Zn2+). The structures of the polymers are characterized by means of fourier transform infrared spectroscopy (FT-IR) and 1H nuclear magnetic resonance (1H NMR) spectroscopy, the results show good agreement with the proposed structures. Thermogravimetric analysis measurements exhibit that the metal coordination polymers possess good thermal stability with high thermal decomposition temperature (thermally stable up to 405–510°C). More importantly, the thermal decomposition temperature of Py-N-PBIS-(Co2+, Ni2+, Zn2+) can be nondestructively detected by taking advantage of the fluorescence quenching effect of metal coordination to 2,6-Bis(2-benzimidazolyl)pyridine structure.

Summary The concern with fluorescent heterocyclic compounds has been growing because they can be utilized in dye‐sensitized solar cells (DSSCs) as organic photosensitizers. As a result of the experiment we conducted, the following outcomes emerged: new fluorescent heterocyclic systems 3H‐benzofuro[2,3‐b]pyrazolo[4,3‐f]quinolines ensued from reaction of 1‐alkyl‐5‐nitro‐1H‐indazole with 2‐(benzofuran‐3‐yl)acetonitrile in KOH/MeOH. New heterocyclic compounds were characterized through a use of elemental analysis and spectroscopic data. The results of the optical properties of the fluorescent compounds demonstrated that their fluorescence quantum yields are comparable to the quantum yields of such well‐known fluorescent dyes as fluorescein. Furthermore, the cyclic voltammetry revealed the electrochemical attributes of the fluorescent heterocyclic systems and that reversible oxidation waves are observable in their case. In order for their photovoltaic performance parameters to be determined, the I‐V curves and the IPCE spectra of the new compounds were launched into an investigation. What followed exposed that the photovoltaic performances of the foregoing compounds were 5.01% to 5.17%.
