Ultrafast solvation dynamics of 12′-apo-β-carotenoic-12′-acid in [C6mim]+[Tf2N]− [PDF]
Chemical Physics, 2010 Abstract Intra- and intermolecular relaxation pathways of 12′-apo- β -carotenoic-12′-acid, an apocarotenoid with terminal carbonyl substitution, were identified after photoexcitation using ultrafast pump-supercontinuum probe spectroscopy in the 350–750 nm range.

Impact of photocatalysis on carotenoic acid dye-sensitized solar cells
Hybrid Materials, 2015 AbstractSensitized mesoporous titania is of increasing interest for catalysis and photovoltaic devices such as dye-sensitized solar cells (DSCs). For photovoltaic applications, the catalytic properties of TiO2 can cause degradation of the dyes during device fabrication. This is especially the case if natural sensitizers are used.

Electrical Properties of Langmuir Films of Fatty Acid Salts and Carotenoic Acid [PDF]
Bulletin of the Chemical Society of Japan, 1978 Abstract Electric conductivities have been studied for Langmuir molecular layers of barium salt of fatty acids and for the layers of barium arachidate mixed with all-trans-β-apo-8′-carotenoic acid. These results have been interpreted based on an electron tunneling model taking account of the mirror image force.
