This subject has gained relevance because of the various applications of bis-phenols which may involve some simple molecules or complex macromolecules containing the bis-phenol framework. The work described in this thesis, “Synthesis, structure and properties of a few bis-phenols and diaryl quinone methides” details some of the important findings related to the synthesis of bis-phenols from phenol, 2,6-dimethylphenol and 2-naphthol. This thesis focusses on the structures and properties of the bis(4-hydroxy-3,5-dimethylphenyl) (aryl) methane, which hitherto has not been studied systematically. This study draws importance from another fact that this compounds can be precursors to diaryl quinone methides. With a view to define such study we introduce a brief review of the state-of –art of bis-phenols and the different aspects related to the synthesis, structure, properties and applications and their analogs in the first chapter. The supramolecular assemblies from bis-phenols are also analysed with suitable examples to illustrate the versatility of these molecules.enCHEMISTRYThesis
