—— | 5-(4-Butylphenyl)-2-[4-(4-butylphenyl)-5-formyl-1-(2-trimethylsilylethoxymethyl)imidazol-2-yl]-3-(2-trimethylsilylethoxymethyl)imidazole-4-carbaldehyde | 591751-02-9 | C40H58N4O4Si2 | 715.096 |
A series of expanded porphyrins, incorporating biimidazoles and bipyrroles within their macrocyclic framework, has been synthesized. Insights into the complex conformational characteristics of these ems were obtained from two-dimensional NMR spectroscopic studies. The relative energy values for the various asymmetric structures inferred from these analyses were compared using DFT molecular modeling calculations.Key words: macrocycles, expanded porphyrins, imidazoles, pyrroles, biimidazoles, supramolecular chemistry, heterocycles.
