All in the twist : Unusually large Stokes shifts and nonlinear optical properties are exhibited by furan‐containing teraryl cyclophene derivatives (see picture). These cyclophenes have neither particularly strong electron‐donating nor electron‐withdrawing groups and have low polarity. DFT calculations have shown that the unusual photophysical properties are dictated by twisted π systems in the teraryl systems and the bridging double bond.
