Synthesis of some New Tetra-aryl Porphyrins for Studies in Solar Energy Conversion. Part 2. Asymmetric Porphyrins
Milgrom, Lionel R.
, p. 1483 - 1487 (2007/10/02)
The synthesis and characterisation of some asymmetrical meso-substituted porphyrins, for studies in solar energy conversion, are described.Isomeric porphyrins (5) and (6) could be cleanly separated and distinguished by the number of 13C n.m.r. resonances for the pyrrole α-carbon atoms.Similarly, 13C and 1H n.m.r. spectrometry was used to characterise a porphyrin with n-pentadecyl and benzoquinone meso-substituents, using the number of pyrrole α-carbon and β-hydrogen resonances.Thin films of porphyrin (11) coated onto glass slides fluoresced, indicating little or no concentration quenching in the coat.
