Synthesis of mono-and bis(1,1'-bi-2-naphthocrown)ethers containing bis(2,6-methylene)anisyl subunit in the crown ring were developed. These chiral macrocycles are suitable precursors to introduce chromogenic function, as exemplified by two novel crowned azophenol chromoionophores. Their coloration process induced by various achiral and chiral amines was studied by UV-vis spectrophotometry.
