Synthesis and fluorescence emission properties of a bis-anthracenyl macrotricyclic ditopic receptor. Crystal structure of its dinuclear rubidium cryptate

Abstract

The new macrotricyclic ditopic bis-anthracenyl receptor (1) displays remarkable fluorescence properties (dual emission: ‘monomer’ and excimer type) which are strongly and selectively modified by binding RbClO₄ and 1,7-diaminoheptane dihydrochloride.
