- Abstract:
- Anthracene- and thiophene-containing PPE-PPV systems, bearing asymmetric
alkoxy side chains, which are presumed to ensure optimal interfacial contact
with PCBM([6,6]-phenyl C61 butyric acid methyl ester) in bulk heterojunction solar
cells, have been synthesized and characterized. The polymers exhibit high molecular
weights with polydispersity indices around 2. The effect of the position of the
aromatic rings on their photophysical properties was found to be very pronounced in
the case of the anthracene-containing polymers, but less significant in the case of the
thiophene-containing counterparts.
