“…Among the structurally diverse range of organic photochromes including fulgides, spiropyrans, overcrowded alkenes, dihydroindolizines, catenanes, etc., the synthetic versatility, thermal stability, and combination of electro-and photosensitive properties place diarylethenes as a key structural unit. 1,2 The systematic study of their spectral, physical, and electronic properties and the design and synthesis of new diarylethene molecules 1,2 has led to the widespread application of these switches in molecular electronics, [3][4][5][6] molecular magnetism, 7 fine chemical synthesis, 8 cell biology, 9 and spectroscopy. 1 These studies over the past decade have led to the design and fabrication of molecular devices, based on diarylethenes, in which the electrical conductivity in nanojunctions can be controlled.…”
