Abstract
The influence of the additives to the thin film of the semiconducting polymer PCDTBT on the kinetics of its photooxidation in air was revealed through changes in the UV–vis absorption spectra and the EPR spectra of the paramagnetic defects. These defects appeared in the initial stage of the PCDTBT photooxidation, and the kinetics of their generation and decay reflected the impact of the additives on PCDTBT stability. While a small amount of PCBM and beta-carotene resulted in the accelerated photooxidation, the addition of fluorinated carbon nanotubes stabilized PCDTBT.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
