Abstract
An extended challenge is to control the supramolecular interaction and get information beyond molecules. An intriguing selfassembly of a perylene-3,4,9,10-tetracarboxylic acid diimide (PDI)- based novel bolaamphiphilic probe is experienced within an artificial environment restrained by supramolecular crystallization and molecular recognition. The bolaamphiphile with hydrophilic 18- azacrown ether ring produced nano-aggregates following different solubility in organic and aqueous media. A structural evolution was observed in the presence of alkali metal ions as guest. The metalcomplex form pseudo cationic structure which further involved in ionic self-assembly with biomolecules, resulting new spectroscopic information on dye self-assembly. The overview of this work is to point out the importance of the supramolecular adaptability concept that has been used to establish an environment friendly behaviour under non-covalent forces leading to evolve new assembly structures and photo-physical properties.
