Abstract

Mannich bases were obtained in yields up to 98% by a multicomponent reaction between β-naphthols, paraformaldehyde and cycloalkylamines under mechanosynthesis conditions in a ball mill. Structure of the products was proven by 1H and 13C NMR spectroscopy methods. The photophysical properties of some of the obtained compounds were studied, a strong fluorescent response towards picric acid was shown with a Stern–Volmer constant of Ksv ≈ 0.7 × 105 M–1.
