Provided are sulfated pillararenes and methods of making and using same. The pillararenes have macrocycle core having a plurality of aryl groups, attached (e.g., covalently bonded) in a para orientation to the adjacent methylene groups. The pillararenes have a hydrophobic cavity. The hydrophobic cavity may be used to sequester various materials or to deliver materials sequestered therein.

Surfactants of the general formula (I) in which R.sup.1 is a linear or branched akyl radical having 6 to 20, especially 10 to 16 C atoms, R.sup.2 and R.sup.3 independently of one another are H or H.sub.3CO, and M is hydrogen, an alkali metal or a moiety N.sup.+R.sup.4R.sup.5R.sup.6, in which R.sup.4, R.sup.5 and R.sup.6 independently of one another are hydrogen, an alkyl group having 1 to 6 C atoms or a hydroxyalkyl group having 2 to 6 C atoms, are readily incorporated into laundry detergents or cleaning products, possess outstanding performance qualities and can be prepared on the basis of renewable raw materials. ##STR00001##
