    2019-5-26 · Zinc dipyrrin complexes with two identical dipyrrin ligands absorb strongly at 450–550 nm and exhibit high fluorescence quantum yields in nonpolar solvents (e.g., 0.16–0.66 in cyclohexane) and weak to nonexistent emission in polar solvents (i.e., <10–3, in acetonitrile). The low quantum efficiencies in polar …

    2004-8-2 · The number and position of chlorine atoms around the aromatic nuclei distinguish each specific congener. In total, there are 75 possible PCDD congeners and 135 possible PCDF congeners. The most widely studied of the PCDDs and PCDFs is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), as it has the highest toxicity of this …

  • Nucleophilic Aromatic Substitution (SNAr) and

    The nucleophilic substitution of aromatic moieties (S N Ar) has been known for over 150 years and found wide use for the functionalization of (hetero)aromatic systems. Currently, several “types” of S N Ar reactions have been established and notably the area of porphyrinoid macrocycles has seen many uses thereof. Herein, we detail …
