Rod-coil amphiphilic diblock copolymers consisting of oligo(2,5-di-n-octyloxy-1,4-phenylenevinylene)
(OPV) as a rod and a hydrophobic block, and poly(ethylene oxide) (PEO) as a coil and a hydrophilic block
were synthesized by a convergent method. The aggregation behavior of the block copolymers in a
selective solvent (THF / H2O) was probed by utilizing the absorption and the emission of the OPV block.
With increasing H2O content, the absorption maximum was blue-shifted, the emission from the
molecularly dissolved OPV decreased, and that from the aggregated OPV increased. The transmission
electron microscopy observation revealed that the block copolymers with the PEO weight fractions of 41
and 62 wt% formed cylindrical aggregate with a diameter of 6-8 nm and a length of several hundreds
nanometer, while, the block copolymer with 79 wt% of PEO fraction formed distorted spherical aggregates
with an average diameter of 13 nm.
