Abstract The first chapter is a review of fluorescent sensors for explosives detection and ion pair receptors. In the second chapter, two novel pyrene-appended calix[4]pyrroles are reported. Their binding properties to various guests including aromatic explosives and anions are discussed. The third chapter describes the design and synthetic attempts of two calix[4]arene-strapped calix[4]pyrroles to serve as ion pair receptor in order to be selective for potassium salts and sodium salts, respectively
