Multi-armed compounds (e.g. Hexapus molecules) have six long alkyl chains with terminal ionic groups, attached to a core benzene molecule, and behave like crown ethers, cryptands, or micelles. The number of the arm can be increased with a mathematical growth progression (e.g. 1→3→9→27) by using new synthetic methodology named cascade syntheses, which is a stepwise procedure to yield the multibranched macromolecules. This new type of compounds (cascade molecules) have a spherical polyfunctionalized surface over a lipophilic core and would be an ideal model compound of unimolecular micelles. This article deals with two types of cascade molecules : Arborols and Dendrimers.
