abstract = {Targeted control of the aggregation, morphology and optical
properties of conjugated polymers is critical for the
development of high performance optoelectronic devices.
Here, self-assembly approaches are used to strategically
manipulate the order, conformation and spatial distribution
of conjugated polymers in solution and subsequently prepared
thin films. The supramolecular complex organisation of
phosphonium-functionalised homo- (P3HTPMe3) and diblock
(P3HT-b-P3HTPMe3) ionic conjugated polythiophenes upon
solvent-mediation and co-assembly with oppositely charged
surfactants is investigated. UV/Vis absorption and
photoluminescence spectroscopies, small-angle neutron
scattering (SANS), cryo-transmission electron microscopy
(cryo-TEM) and atomic force microscopy (AFM) are used to
probe the organisation and photophysical response of the
aggregates formed. Subtle differences in the surfactant mole
fraction and structure, as well as the solvent polarity,
yield differences in the nature of the resultant
homopolyelectrolyte-surfactant complexes. In contrast, only
moderate structural transformations are observed for the
amphiphilic diblock copolyelectrolyte, emphasising the
structure “anchoring” effect of a neutral polymer block
when amphiphilic copolymers are dissolved in polar solvents.
These results highlight the versatility of self-assembly to
access a range of nanomorphologies, which could be crucial
for the design of the next generation of organic
optoelectronic devices.},
