The neutral form of porphyrin P was synthesized as described before, followed by separation and isolation of the α2ß2 atropisomer. and pretreated with 20 eq. of TFA to obtain the hexacationic P which was used for all of the experimental studies. UV-Vis absorption spectra were recorded using a Specord 250 spectrophotometer from Quartz Glass 10mm 6030-UV (1 cm path length quartz cell). ECD spectra were recorded on a Jasco spectrophotometer using scanning rate 50, nm/min, bandwidth 1 nm, response time 1 s, accumulations 5 scans.
