The homopolymeric sequence formed by the head‐to‐head association of tetrakisporphyrin 1 is completely dissociated by the competitive association of the ditopic guest G2, resulting in the supramolecular copolymer poly‐1⋅G2 with an alternatingly repeating host–guest sequence. The 1:1 stoichiometry of 1 and G2 is confirmed by a Job plot using UV/Vis titration and diffusion‐ordered NMR spectroscopy (DOSY)...
Netzwerke bilden: Ein Diporphyrin, das eine elektronenarme Gast‐Einheit trägt, bildet große polymere Aggregate mit Kopf‐Schwanz‐Anordnung, wie mittels Diffusions‐NMR‐Spektroskopie und Viskositätsmessungen bestätigt wurde. Im Festkörper werden weitverzweigte Nanonetzwerke beobachtet (siehe Bild).
