yield. The porphyrin gave a highly modified UV–vis absorption spectrum with three strong bands showing up in the Soret region and a series of Q bands that extended beyond 700 nm. The proton NMR spectrum also showed a significantly reduced diamagneticringcurrent where the meso-protons gave resonances near 9.3 ppm instead of typical porphyrin values of 10 ppm.
