    An Analysis of Porphyrin Molecular FlexibilityUse of Porphyrin Diacids by Beisong Cheng (2970567)

    Published 1997
    “…Molecular mechanics calculations, using a modified version of MM2(87) and a newly developed force field for porphyrin diacids, correctly predict that the flexibility of <i>meso</i>-tetraaryl porphyrin diacids decreases as the steric bulk of the peripheral substituents increases:  [H<sub>4</sub>TPyP]<sup>2+</sup> ≈ [H<sub>4</sub>TPP]<sup>2+</sup> > [H<sub>4</sub>T-2,6-(OH)<sub>2</sub> PP]<sup>2+</sup> ≈ [H<sub>4</sub>T-2,6-F<sub>2</sub> PP]<sup>2+</sup> > [H<sub>4</sub>T-2,6-Cl<sub>2</sub> PP]<sup>2+</sup> ≈ [H<sub>4</sub>TMP]<sup>2+</sup>. …”
