Diacenaphtho[1,2-c:1′,2′-e]-1,2-dithiin: synthesis, structure and reactivity

Fusion of Phosphole and 1,1′‐Biacenaphthene: Phosphorus(V)‐Containing Extended π‐Systems with High Electron Affinity and Electron Mobility

“…To reveal the optical and electrochemical properties of the present π‐systems, UV/Vis absorption/fluorescence spectra and redox potentials of 3 – 7 and thiophene analogue 8 13 were measured in CH 2 Cl 2 (Table 1, Figure S2 and S3 in the Supporting Information). The lowest π–π* transitions of 4 a , b appeared at longer wavelengths than the corresponding transition of 8 .…”
