15-Crown-5 (IUPAC 1,4,7,10,13-pentaoxacyclopentadecane) 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+)[1] and potassium (K+),[2] but selective binding to lead (Pb2+).
As a functional group, research has been conducted to probe its application in liquid crystalline studies,[3] ion-selective membranes[1],[4] chromo- and fluoroionophores.[5]
