The first synthesis of a molecule with this property was performed by Herges et al.
The first synthesis of a molecule with this property was performed by Herges et al. A Polish group synthesized a compound which contains para- phenylene rings attached to a porphyrin group that is able to rapidly interconvert between this property and a similar property. A set of rules formulated by Dewar and Zimmerman that include this property can be considered a form of the Woodward Hoffman rules that take it into account. This concept was first introduced by Heilbronner, who showed that it can arise when n atomic orbitals are each at an angle of pi over n with respect to the ring, and it is only possessed by systems which have 4n pi electrons, which violates Huckels rule. For 10 points, identify this property possessed by certain organic molecules which lack planarity, and is named for some mathematician with a one dimensional strip.
