Perylenetetracarboxylic diimide derivatives bearing 2- or 4-peripheral pyrrole pendants could be efficiently crosslinked to form an insoluble film either by electropolymerization or visible light induced oxidative photopolymerization of the pyrrole units.

Abstract In this work, a human sweat-based wearable sensor for real-time glucose monitoring has been fabricated on cotton substrate after treating it with two-step polymerization of pyrrole. The pyrrole-treated fabric was coated solution copper sulphate pentahydrate to grow Cu layer. cotton/pyrrole/Cu treated the solutions acetate and manganese form Cu–Mn transition-metal alloy via electrochemi...

Novel chemical and biological sensors based on a single poly(pyrrole)-NTA chelator nanotube for sensitive, selective, rapid and real-time detection of histidine-tagged protein and cupric ions are reported. NTA groups on the nanotube surface provided a simple mechanism for metal ion sensing via the high-affinity interaction between NTA and the subsequent detection of histidine-tagged protein thr...

Electronic excitation spectra of furan and pyrrole are reinvestigated by the symmetry-adapted cluster configuration-interaction method. The 47 and 46 lowest singlet and triplet electronic states are computed for furan and pyrrole, respectively. Two series ~1a2 and 2b1! of low-lying Rydberg states and the valence p–p* excited states strongly influence each other in both furan and pyrrole. The pr...

Near edge x-ray absorption fine structure spectra have been measured at the carbon and nitrogen K-edges of the prototypical aromatic molecule, pyrrole, both in the gas phase and when solvated in water, and compared with spectra simulated using a combination of classical molecular dynamics and first principles density functional theory in the excited state core hole approximation. The excellent ...

Electrical sensitivity of a beryllium oxide nanotube (BeONT) was examined toward (C4H5N) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31(d) level, and it was found that the adsorption energy (Ead) of pyrrole on the pristine nanotubes is   a bout -48.58kcal/mol. But when nanotubes has been doped with S and P atomes , the adsorptio...

BACKGROUND New animal models of chronic pulmonary hypertension in mice are needed. The injection of monocrotaline is an established model of pulmonary hypertension in rats. The aim of this study was to establish a murine model of pulmonary hypertension by injection of the active metabolite, monocrotaline pyrrole. METHODS Survival studies, computed tomographic scanning, histology, bronchoalveo...

Nature has devised many different biosynthetic pathways towards pyrrole rings. Next to the well-studied aminolaevulinic acid based biosynthesis of the porphyrins, it was shown that in the prodigiosins (3) each of the pyrrole rings is build in a different way, starting from proline, serine, glycine and acetate. Proline is also the pyrrole precursor in streptopyrrole, however, the carbonyl group ...
