A new type of pseudo-living polymerization by continuous addition of the monomers in the addition-condensation of 1-methylpyrrole and aldehydes has been studied. This polymerization is able not only to control the structure of the polymer such as block and branched, but also to introduce functional groups such as energy donors and acceptors. We show two types of polymers that are used in photochemical studies, which suggest that the materials prepared from this new type of polymerization may be useful in artificial photosynthesis. The first is an A, B-block amphiphilic polymer in which the energy donor and acceptor are each in the different blocks. This polymer shows an interphase photoinduced energy transfer in a micellar system. The second polymer is a branched polymer, with a high number of energy donor units in the branches and a low number of energy acceptor units in its center that is also bearing electron donor-acceptor units. The polymer combines efficient light harvesting with photoinduced electron transfer.
