title: Synthesis and electronic structure of dicyanofulvene-fused electron accepting molecule based on a 1,5-dihydro-s-indacene framework.
abstract: A novel dicyanofulvene dimer fused to a benzene ring (3a) has been synthesized as an electron-accepting molecule. The low-lying LUMO level was validated by measuring the ultraviolet photoelectron spectroscopy and electronic spectra. Cyclic voltammetry exhibited sequential reversible waves from 3a to 3a(4-) in a range of -0.30 to -2.14 V (vs Fc/Fc(+)). The electronic structure of 3a and its anionic species (3a(•-), 3a(2-), 3a(3•-), and 3a(4-)) were investigated by electronic spectra and X-ray crystallographic analyses.
