The synthesis of a block copoly(3-alkylthiophene)
consisting of
two different P3AT blocks equipped with an H-donor and -acceptor functionality
is presented. The P3ATs were synthesized using a functionalized Ni-initiator.
By a series of postpolymerization reactions, including click chemistry,
an H-donor and -acceptor entity was attached to the end of the polymer
chains. Evidence for a quantitative functionalization of the polymers
was provided by <sup>1</sup>H NMR and MALDI-ToF analyses. Chiral side
chains were implemented on one of both blocks, allowing the study
of the influence of the H-bond formation on the chiral self-assembly
using UV–vis and circular dichroism spectroscopy
