PI-CONJUGATED MACROCYCLIC COMPOUNDS: SYNTHESIS AND AROMATICITY

Abstract

Aromaticity is a fundamental concept in organic chemistry that significantly influences the chemical structure, reactivity, and stability of molecules. Understanding the aromatic nature of polycyclic aromatic hydrocarbons (PAHs), including both closed-shell and open-shell varieties, is essential for comprehending their stability and chemical behaviours. This thesis focuses on the synthesis and characterization of various fully ?-conjugated macrocycles and examines how different electronic structures affect their properties. This thesis gives a comprehensive analysis of the intrinsic properties of open-shell and closed-shell polycyclic aromatic hydrocarbons (PAHs) especially macrocycles. Key concepts such as valence tautomerization and aromaticity in these macrocycles are meticulously examined. Our aim is to delineate the intricate interplay between the molecular configurations of these compounds and their characteristics. This in-depth understanding is crucial for expanding our scientific knowledge and may drive the development of innovative applications for these macrocycles.
