Abstract

Abstract: We report the self‐assembly and isolation of two metallamacromolecular constitutional isomeric pairs based on connectivity. Utilizing a robust dimer with varying substitution to the core benzene ring resulted not only in the isolation of the expected 60°‐oriented tetramer and 120°‐oriented hexamer but also in the unexpected isolation of a 60°‐oriented hexamer and a 120°‐oriented tetramer. These isomers were characterized by 1 H NMR spectroscopy and mass spectrometry (ESI‐travelling wave ion mobility), which revealed significant structural differences. Molecular modeling was utilized to aid in characterization. Abstract : Two metallamacromolecular constitutional isomeric pairs were self‐assembled based on connectivity.
