“…Diarylethene has been extensively reported as photoswitching units for single-molecule optical switching devices. [1,[108][109][110][125][126][127][128][129][130][131][132] These compounds exhibit exceptional thermal stability, fatigue resistance, high cyclization, and light chemical sensitivity. Diarylethene can undergo transitions between open-ring and closed-ring states upon exposure to different wavelengths of absorption spectroscopy light, [130] demonstrating effective photochromic behavior in both solutions [16] and solid states.…”

Electronic switches have been considered to be one of the most important components of contemporary electronic circuits for processing and storing digital information. Fabricating functional devices with building blocks of atomic/molecular switches can greatly promote the minimization of the devices and meet the requirement of high integration. This review highlights key developments in the fabrication and application of molecular switching devices. This overview offers valuable insights into the switching mechanisms under various stimuli, emphasizing structural and energy state changes in the core molecules. Beyond the molecular switches, typical individual metal atomic switches are further introduced. A critical discussion of the main challenges for realizing and developing practical molecular/atomic switches is provided. These analyses and summaries will contribute to a comprehensive understanding of the switch mechanisms, providing guidance for the rational design of functional nanoswitch devices toward practical applications.

“…[10] Quinazolinones are an important class of compounds with notable photophysical properties, widely used in the design of new organic materials. They find use as fluorescent probes and dyes, [11][12][13][14][15] molecular switches [16] and even in organic lightemitting devices. [17,18] Owing to their commercial availability and intricate electronic structure bringing about their photochemical properties, many approaches for their functionalization were developed.…”

Cyclopentadienyl manganese tricarbonyl (cymantrene) is known to undergo photochemical reactions by releasing one of its CO ligands. Here we present the first example of a photorearrangement of a cymantrenylmethyl fragment, where it retains all its three CO ligands. A tandem experimental and DFT (density functional theory)-based computational investigation allows us to explain this unexpected behavior: the rearrangement, indeed, begins with the release of one CO ligand, but cage effect of the solvent captures this CO molecule, allowing it to rapidly reattach once the rearrangement takes place.

“…During the past decade, a number of works were focused on the photochromic compounds due to their potential applications in optical switches and memories [1][2][3][4]. Since the development of the photochromic compounds, diarylethenes have drawn greater attention on photocontrollable elements in molecular devices and switches [5][6] Because of their distinguished thermal stability [7] and remarkable fatigue [8] resistance of the cyclization and cycloreversion reactions, Photochromic materials can reversibly interconvert between open ring and closed ring conformations [9].…”

Abstract.A new symmetrical photochromic diary lethene 1 , 2 -bis ( 2 -menthy l-5 -( trImethyls ilylacetylene)-3 -thienyl) perfluorocyclopentene (1o) based on a dithiophene structure has been constructred, and the photochromic and fluorescent properties of 1 were investigated. The results indicated diarylethene 1o showed good photochromism and notable fluorescence switching, which make it possible potential application in optical recording.
