A non-rotatory isomerization path in ethene derivatives? Investigation of a stilbenophane and protonated azobenzenophanes (“pseudo-stilbenophanes”)†‡
Abstract
A stilbenophane and protonated azobenzenophanes (“pseudo-stilbenes”) with four –CH2–S–CH2– bridges in all meta-positions were synthesized. The spectroscopic and photochemical properties were investigated: excited dimer
