Cascadyl

Rule 3 If a molecule contains one dendritic structure part or only different ones, the dendritic structures (=dendrons) are treated as substituents and are assigned the suffix -cascadyl. If at least two dendrons in a molecule are of the same kind, then the name is given the suffix -cascadane (Fig. 1.22). 

Friedhofen and Vogtle have recently outlined a detailed nomenclature for dendrimers which is discussed in the Section Key Reference. In brief, a dendrimer is defined as comprising a series of self-resembling units, termed dendrons, linked by a common core. The dendrons are referred to as cascadyl-substituents or, if there is more than one identical dendron, the molecule is termed a cascadane.
