| abstract |
A process for modifying at least one dendron intended to form part of a dendrimer, said dendron having the formula: FO(dendrite-Qa)y wherein FO is a functional group attached, either directly or via a linking group which can contain one or more reactable unsaturated units, to the first branching 10 atom or group of the dendrite, each 'dendrite' which may be the same or different is a dendrite which contains branching atoms or groups and optionally linking groups and comprises at least said first branching atom or group which must have, in addition to FO, 2 or more groups attached, at least one of said dendrite or, if present the linking group to FO containing one or more reactable unsaturated units, y is 1 or more, Q is a surface group and a is 0 or an integer, provided that when a = 0 the distal group of each arm of the or each dendrite is a (hetero)aryl group, which comprises reacting at least one said reactable unsaturated group in a chemoselective manner to form a less unsaturated group as well as a process for modifying dendrimers in a similar manner. |
