Polymer with side functional groups

As mentioned above, Pcs can be incorporated as side groups of a main polymeric chain. Two routes can be followed to achieve this goal. One of them involves the polymerization (or copolymerization) of unsymmetrically substituted Pcs, i.e., holding reactive sites at one of the isoindole subunits. The second one requires the preparation of a polymer with side functional groups that can react in a further step with an appropriately functionalized Pc. 

L-24 as a ligand, up to 85—90% yield. The linking reaction of a poly(tBA) with a bromide terminal was also possible with divinylbenzene, whereas the other two divinyl compounds led to side reactions.328 The yield of star polymers can be increased up to 95% with the use of additives. The a-end-functionalized linear polymers afford surface-functionalized star polymers with various functional groups such as alcohols, amines, epoxides, and nitriles.

A variety of soluble and surface-bound polymers with side chain functional groups are available via active ester synthesis according to the general reaction schemes discussed in preceding Sections. Typical examples of such polymers are outlined below.
