Effect of sample preparation and excitation conditions on the single molecule spectroscopy of conjugated polymers

Article Abstract:

New single molecule spectroscopy (SMS) data on the conjugated polymer poly[2-methoxy,5-(2'-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) at low temperature are obtained and the combined effects of sample preparation and excitation condition are investigated. The data helped in describing the discrepancy among various published SMS data on MEH-PPV and has suggested that environmental impurities, long irradiation times, near interfaces.

Controlling optical properties and interchain interactions in semiconducting polymers by encapsulation in periodic nanoporous silicas with different pore sizes

Article Abstract:

The photophysics of MEH-PPV incorporated into the pores of periodic silica hosts is investigated to understand the role played by interchain aggregation and chain morphology in polaron production. The results indicate that polaron production and stability can be simply controlled by modifying polymer chain aggregation and conformation.
