Co-crystals built from macrocycles with pyromellitic diimides and naphthalene derivatives: transformation of a binary co-crystal solvate to a solvate through solvent exchange

Co-crystallization of a macrocycle and 1,5-dihydroxynaphthalene afforded co-crystals with solvents, which, when soaked in diethyl ether, formed crystals of the macrocycle through solvent exchange and the release of 1,5-dihydroxynaphthalene.
