    • Recent investigations of the large red shifts seen in the optical spectra of peripherally crowded nonplanar porphyrins have led some research groups (Wertsching, A. K.; Koch, A. S.; DiMagno, S. G. J. Am. Chem. Soc. 2001, 123, 3932. Ryeng, H.; Ghosh, A. J. Am. Chem. Soc. 2002, 124, 8099) to propose that the observed shifts (and by implication the changes seen in other properties) are simply the result of substituent effects. A recent paper by our group (ref 73) confirms that the large red-shifts seen in peripherally crowded nonplanar porphyrins are indeed caused by nonplanar deformation and shows that the attribution of the red-shifts to substituent effects resulted from the use of inappropriate model structures in the earlier calculations.
