To overcome the limit of synthesis procedure for producing a dendron and a dendrimer with saturated units in the dendron and/or core, to allow use of an optoelectronic device, particularly on OLED.
The invention relates to a method for modifying at least one dendron intended to form part of the dendrimer, the 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 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 the first branching atom or group which must have, in addition to FO, 2 or more groups attached, at least one of the 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 the dendrite or each arm of the each dendrite is a (hetero)aryl group, which comprises reacting at least the one reactable unsaturated group in a chemoselective manner to form a less unsaturated group, as well as a method for modifying dendrimers in a similar manner.
