NMR spectrum. NMR spectrum of the purified melanin pigment synthesized by Streptomyces glaucescens strain NEAE-H (Fig. 7B) shows resonances between 8.0 and 6.0 ppm and between 0.813 and 4.504 ppm. Resonances between 8.0 and 6.0 ppm in NMR spectra are assigned to aromatic ...
a, 1H NMR spectra of DMPESI in anhydrous DMSO-d6 after six months of storage in ambient air. The H2O peak in DMSO-d6 is at 3.3 ppm (vertical dashed blue line): the signal is absent in the samples. The chemical structure of DMPESI is shown. b, Photographs of fresh and 24-mon...
