AI Article Synopsis
- * A detailed step-by-step synthetic method reveals how the N-substituents affect the reactivity of the chemical precursors and intermediates involved.
- * Experimental and theoretical studies show that the properties of the resulting macrocycles vary based on their substitution patterns, with some leading to the formation of unique ribbon-like supramolecular structures.
Article Abstract
Pre- and postintroduction of substituents with respect to the macrocyclization step leads to previously unknown N-substituted azacalixphyrins. The stepwise synthetic approach has been studied in detail to highlight the key role of the N-substituents of the precursors and/or intermediates in terms of reactivity. Based on a combined experimental and theoretical investigation, the relationship between the properties of the macrocycles and their degree of substitution is rationalized. Depending on the nature of the N-substituents, the formation of supramolecular ribbon-like structures could also be observed, as demonstrated by combined TEM, SEM, AFM, and FTIR experiments.
