Vibrational solvatochromism in organic photovoltaic materials: method to distinguish molecules at donor/acceptor interfaces

We report the observation of vibrational solvatochromism in organic photovoltaic materials. The frequency of the carbonyl (CO) stretch of the methyl ester group of the functionalized fullerene, PCBM, is sensitive to the local phase separated morphology of polymer blends and bilayers incorporating the fullerene. In particular, PCBM molecules at interfaces with conjugated polymers exhibit higher frequency carbonyl stretch vibrations in comparison to molecules imbedded in the interiors of PCBM clusters/layers. The resulting frequency gradient was recently used to examine the dynamics of charge photogeneration in a blend of the conjugated polymer, CN-MEH-PPV, with PCBM. In this contribution, we explore the origin of the frequency shift and show that it arises from variations in the inhomogeneous solvent environments experienced by PCBM molecules as a result of phase separation in the polymer blend.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
