Transparent organic image sensors with polarization sensitivity have been demonstrated (see figure). When the light is perpendicularly polarized to the molecular orientation axis, the reflectivity of the imaging objects (white and black) is successfully detected by the photodiodes, which are made of stacked layers of a well‐aligned 3,4,9,10‐perylenetetracarboxylic‐bis‐benzimidazole and non‐aligned titanyl phthalocyanine.
