No full textAbstract The solvent effect on the 1 H NMR spectra of 5, 11, 17, 23 tetra-tert-butyl-25, 26, 27, 28-tetra-[2-(4-pyridyl) Resumen El efecto del solvente en los espectros 1 H RMN de 5, H RMN espectro de este macrociclo es sensible a la naturaleza del solvente. En estos solventes la conformación del ligando corresponde a un cono distorsionado. Los desplazamientos químicos mas pronunciados de los protones aromáticos con respecto a cloroformo son observados en acetonitrilo, nitrometano y piridina.
