meso-tetraalkynylporphyrins

Abstract:

5,10,15,20-Tetra(4-n-butylphenylethynyl)porphyrin has been synthesised from 4-n-butylphenylpropynal and converted into its zinc(II) and lead(II) complexes. The solution electronic spectra of these porphyrins are compared to the analogous complexes of 5,10,15,20-tetra(trimethylsilylethynyl)porphyrin. The aryl rings of the tetra(4-n-butylphenylethynyl)porphyrin extend the porphyrin chromophore, resulting in an increase in the oscillator strength and a bathochromic shift of about 600 cm-1 in all...
