Abstract: C1.00023 : Self-assembly of PtBA-P3HT multi-arms star-like block copolymer at the air/water interface
Author:
A novel PtBA-P3HT multi-arm star-like diblock copolymer (BCP) was
synthesized via a combination of atom transfer radical
polymerization,
quasi-living polymerization and click reaction. The self-assembly of
PtBA-P3HT multi-arm star-like BCP at the air/water interface was
systematically explored using the Langmuir Blodgett (LB)
technique. The
hydrophobic star-like BCP has 21 arms, with PtBA as the core and
P3HT as the
shell. At the air/water interface, the BCP molecules gradually
assembled
into domains composed of bundle-like structures under surface
pressure, and
finally formed the network structure in a way controlled by PtBA
chain
folding and P3HT chain stacking. The photoluminescence
measurement showed
that the formation of P3HT bundle in LB film led to enhanced
luminescence
due to the reduced inter-chain coupling.
