Boron AtomBoron TrifluorideQuantum Chemical StudyAcceptor ComplexDipyrrolylThe geometric parameters and energies of the products of donor-acceptor interaction of dipyrrolylmethenes with BF 3 and other inorganic Lewis acids were calculated by quantum-chemical methods. The bond nature and the energies of...
The quantum-chemical simulation showed that the rigid acetylene spacer gives linear structure to the H 2 L molecule in contrast to the spiral-shaped geometry of structural analogs with -CH 2 - spacer.doi:10.1134/S107036321011023XE. V. Antina...
Fluorescence Quantum YieldPhotophysical PropertyDeuterated ChloroformCopper(II) and cadmium(II) complexes with bis(2,4,7,8,9-pentamethyldipyrrolylmethene-3-yl)-methane were synthesized. Influence of the complex-forming ion nature on the optical properties of [Cd 2 L 2 ] and [Cu 2 L 2 ] ...
We measure the spectral luminescence characteristics (absorption, fluorescence, lasing, phosphorescence, and luminescence excitation spectra; fluorescence and phototransformation quantum yields; lifetimes of long-lived radiation) and estimate the fluorescence radiation constants and lifetimes for new synthesized ...
The formation of donor-acceptor complexes of dipyrrolylmethene and structurally similar biladiene- a,c with boron trifluoride was studied by electronic absorption, IR, and 1 H NMR spectroscopies as well as by quantum chemical calculations. It was shown that the formation of donor-acceptor ...
