Electronic Properties of Optically Switchable Photochromic Diarylethene Molecules at the Interface with Organic Semiconductors.

Optically switchable transistor via energy-level phototuning in a bicomponent organic semiconductor.

Organic semiconductors are suitable candidates for printable, flexible and large-area electronics. Alongside attaining an improved device performance, to confer a multifunctional nature to the employed materials is key for organic-based logic applications. Here we report on the engineering of an electronic structure in a semiconducting film by blending two molecular components, a photochromic d...

Optically addressable transistors by mixing small molecule semiconductors and photoswitches

An international team of researchers led by Stefan Hecht (Member of IRIS Adlershof) and Paolo Samori from the Université de Strasbourg (France), in collaboration with scientists from Stanford University (USA) and the Université libre de Bruxelles (Belgium), demonstrated that high-performance optically switchable field-effect transistors can be developed by blending photochromic molecules with s...

DFT/TDDFT investigation of the modulation of photochromic properties in an organoboron-based diarylethene by fluoride ions.

The diarylethene derivative 1,2-bis-(5'-dimesitylboryl-2'-methylthieny-3'-yl)-cyclopentene (1) containing dimesitylboryl groups is an interesting photochromic material. The dimesitylboryl groups can bind to F(-), which tunes the optical and electronic properties of the diarylethene compound. Hence, the diarylethene derivative 1 containing dimesitylboryl groups is sensitive to both light and F(-...

Design and synthesis of a new class of photochromic diarylethene-containing dithieno[3,2-b:2',3'-d]pyrroles and their switchable luminescence properties.

Photochromic diarylethene as an information processing unit: Magnetic and electric switching

Photochromic compounds reversibly change not only the absorption spectra but also their geometrical and electronic structures. This principle can be applied for the photoswitching of the physical properties of the molecular materials. In particular, photoswitching of the flow of information through the molecule is interesting because information processing using molecular devices is attracting ...
