15-Crown-5 is a crown ether with the formula C10H20O5. It is a cyclic pentamer of ethylene oxide that has been shown to complex with various cations, including sodium (Na+)[2] and potassium (K+),[3] but selective binding to lead (Pb2+).[citation needed]
As a functional group, research has been conducted to probe its application in liquid crystalline studies,[4] ion-selective membranes,[5] chromo- and fluoroionophores.[6]
