Although carbon nanoparticles or quantum dots (C-dots) have been studied extensively for a variety of applications (e.g., photocatalysis, metal ion sensing, antibacterial, cell labeling), greener synthetic method is highly indispensable. Herein, we report facile one-step hydrothermal carbonization approach the synthesis fluorescent blue/green C-dots using oyster mushroom (Pleurotus species). First, demonstrate application these as colorimetric sensor toxic ions detection such heavy Pb2+ with...

Abstract Four different samples of ferrocene‐grafted hydroxyl‐terminated polybutadiene (Fc‐HTPB), containing 0.20, 0.52, 0.90, and 1.50 wt % iron, were synthesized by the Friedel–Crafts alkylation ferrocene with (HTPB) in presence AlCl 3 as a (Lewis acid) catalyst. The effects reaction conditions on extent substitution investigated. Fc‐HTPBs characterized IR, ultraviolet–visible, 1 H‐NMR, 13 C‐NMR spectra. iron content number hydroxyl groups estimated, properties, including thermal...

ABSTRACT Ferrocenyl chalcone complex (Fc 2 L) has been synthesized from the condensation of 3,4:10,11‐dibenzo‐1,13[N,N′‐bis{(3‐formyl‐2‐hydroxy‐5‐methyl)benzyl}]‐5,9‐dioxocyclohexa decane (the precursor compound) with acetyl ferrocene. The Co(II) and Cu(II) Complexes (CoFc L [ 1 ] CuFc ]) were ferrocenyl metal chloride salts characterized by various physicochemical techniques (UV–Vis, FT‐IR, H NMR, 13 C ESI‐MS, TGA). electrochemical studies exhibit a quasireversible reduction wave E pc near...

Abstract Two fluorescent chemosensors, denoted as chemosensor 1 and 2 , were synthesized subjected to comprehensive characterization using various techniques. The techniques employed Fourier‐transform infrared (FTIR), proton ( H)‐ carbon‐13 13 C)‐nuclear magnetic resonance (NMR) spectroscopy, electrospray ionization (ESI) mass spectrometry, single crystal X‐ray diffraction analysis. Chemosensor is composed of a 1H ‐imidazole core with specific substituents, including...
