“…Fourier transform-infrared analysis showed characteristic intensity reduction of IR bands with hole doping, 39−41 which were almost fully recovered upon exposure to pyrrole (Figure S15). In addition, IR bands corresponding to irreversible oxidation products such as sulfoxides, sulfones or sulfonic acids, 42 unsaturated hydroperoxides, or carboxylic acid derivatives 43 were not found in both cases. These results indicate that the chemical integrity of the film is maintained after a redox cycle for both oxidants.…”

Dynamic colors that respond to environmental changes are of great interest for diverse areas of science and technology ranging from chemical and biological sensors to smart information display. Here, we demonstrate a multitude of responsive colors from a conjugated polymer film arising from a thin-film interference. This mechanism provides an excellent control over the thin-film color by varying the film thickness, type of substrate, and degree of polaron population and is generally applicable to various conjugated polymers for further color variation. Furthermore, multiple sets of responsive colors are achieved from a single polymer layer by patterning the underlying substrate to spatially modify the interference conditions. Using this system, we demonstrate the reversible color changes induced by an oxidative or reductive environment with color responsivity controllable with the nature of the polaron state.

Photodetectors are a key sensing component in enabling emerging technologies. For weak light detection, phototransistors with high responsivity are needed. Furthermore, the ability to fabricate phototransistors using solution processing techniques will enable new form factors, including flexible and large‐area devices. In this work, a novel approach for synthesizing a photosensitive organic/inorganic hybrid semiconducting thin film through solution processing is introduced. The approach involves hierarchical patterning of semiconducting carbon nanotubes (CNTs) with poly(3‐hexylthiophene‐2,5‐dyl) (P3HT) through solution‐phase heterogeneous crystallization. The fabricated hybrid phototransistors are qualified through electrical testing at varied illumination profiles within the visible light range. At a wavelength of 470 nm with an optical excitation power of 0.37 µW cm−2, the device exhibits photoresponsivity of 3.53 × 105 AW−1, surpassing other solution‐processed, non‐lead‐containing devices in the literature. The optical response extends from both photogating (low excitation power) and photon‐induced carrier generation (high excitation power). The detectivity of the device is ≈8.7 × 1010 Jones. The transient response includes a rise time of 100 ms and a fall time of 200 ms which is similar to the metrics of other low‐dimensional photodetectors. These findings highlight the prospects of the solution‐processed P3HT/semi‐CNT hybrid platform for advanced photodetection applications with flexible and large‐area form factors.
