Deuterium-labeled fullerene derivatives can be used to study the composition of the active layer in OPV devices in great detail. At Solenne, we can prepare such D-labeled compounds, including d5-PCBM, d5-PCBM, D-labeled bisPCBM, and D-labeled ICBA. Some of these compounds are available directly from stock. For d5-PCBM, the D-labeling is on the phenyl ring. In this way, the label is at a stable position in the molecule. All 5 hydrogen atoms are replaced by deuterium atoms, thus having a high degree of labeling (>99.5%), for easy detection.
