Part of a molecule with only one free valence, comprising exclusively dendritic and terminal constitutional repeating units and in which each path from the free valence to any end-group comprises the same number of constitutional repeating units.
Notes:
- For the purpose of determining the nature of constitutional repeating units the free valence is treated as a connection to a CRU.
- A dendrimer molecule comprising only one dendron is sometimes referred to as dendron, monodendron or functionalised dendron. The use of the terms ‘dendron’ or ‘monodendron’ in the meaning of molecule or substance is not acceptable.
- In a dendron, macrocycles of constitutional units are absent.
Example of a regular dendron, highlighting dendritic constitutional repeating units, terminal constitutional repeatingunits, end-groups, the dendron direction and the free valence. The preferred constitutional repeating unit is chosen such that the branch points are at its end in the dendron direction.
