Covalent Organic Functionalization of Graphene Nanosheets and Reduced Graphene Oxide via 1,3-Dipolar Cycloaddition of Azomethine Ylide [PDF]
Nanoscale Advances, 3, 2021, 5841-5852, 2021 Organic functionalization of graphene is successfully performed via 1,3-dipolar cycloaddition of azomethine ylide in the liquid phase. The comparison between 1-methyl-2-pyrrolidinone and N,N-dimethylformamide as dispersant solvents, and between sonication and homogenization as dispersion techniques, proves N,N-dimethylformamide and homogenization as ...

[(Pyrrolidin-1-yl)carbothioylsulfanyl]methyl pyrrolidine-1-carbodithioate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 The title compound, C(11)H(18)N(2)S(4), was unexpectedly obtained during studies on the reactivity of the complex tris-(acac-κ(2)O,O')gallium(III) (acac is acetyl-acetonate) with C(4)H(8)NCS(2)H in dichloro-methane. The title compound shows disordered two pyrrolidine rings with major and minor occupancies of 0.546 (4) and 0.454 (4).

Pyrrolidine dithiocarbamates of Pd(II) [PDF]
Inorganica Chimica Acta, 2005 The dithioester (CH2)4NCS2CH3 (PyDTM, 1-pyrrolidinecarbodithioate methyl ester) has been prepared by reaction of the parent ammonium salt NH4PyDT (PyDT=(CH2)4NCS2 with methyl iodide in water/ethanol. The reaction of PyDTM with PdCl2 allowed to synthesize either (PdCl2(PyDTM)), in which the ligand is chelated by both sulfur atoms, or(PdCl2(PyDTM)2), in ...

Photophysical Properties of BODIPY-derivatives for the Implementation of Organic Solar Cells: A Computational Approach [PDF]
, 2021 Solar cells based on organic compounds are a proven emergent alternative to conventional electrical energy generation. Here, we provide a computational study of power conversion efficiency optimization of BODIPY-derivatives by means of their associated open circuit voltage, short-circuit density, and fill factor.
