“…In order to avoid the interference between the sequentially imposed light beams (accumulation effect in general) and to guarantee the precise demodulation of the optical signals, the device was erased with an electrical pulse after reading each light bit. With the two degrees of freedom of a single light beam to carry the digital information, which can be readily read and stored by the present optical demodulator and memory devices, the operation for both the optical‐modulator and demodulator can be simplified as compared to those only capable of using one degree of freedom and larger numbers of light beams to transmit an eight‐bit code . The other letters of the alphabet can be demodulated similarly.…”

An Optoelectronic Resistive Switching Memory with Integrated Demodulating and Arithmetic Functions

A multifunctional optoelectronic resistive switching memory, composed of a simple ITO/CeO2- x/AlOy/Al structure, is demonstrated. Arising from the photo-induced detrapping, electrode-injection and retrapping of electrons in the CeO2-x/AlOy/Al interfacial region, the device shows broadband, linear, and persistent photoresponses that can be used for the integration of demodulating, arithmetic, and memory functions in a single device for future optoelectronic interconnect systems.

Colorimetric and fluorescent chemosensors have been actively studied in recent years, and this article covers our contributions to colorimetric and fluorescent chemosensors in detecting anions, metal ions, reactive oxygen species (ROS), reactive nitrogen species (RNS), biothiols, and gases. The chemosensors discussed in this article are categorized according to their corresponding analytes, and the final part is devoted to polydiacetylene-based chemosensors. We hope that this article will be beneficial in the design of chemosensors for various important analytes.

“…In this way, the information data are coming on-stream, which can be read on an “on-off” manner based on Malus' law ( I = I 0 cos 2 θ ). In contrast with common light-driven molecular logic gates in solution 49 , the incorporation into polymer matrix can provide a route toward all solid-state systems for fabricating a layer of all-photonic logic 50 , especially in encoding optical signals 51 and transistor sensors 52 .…”

Enantiospecific photoresponse of sterically hindered diarylethenes for chiroptical switches and photomemories

Light-driven transcription, replication and enzyme catalysis are critically dependent upon a delicate transfer between molecular and supramolecular chirality. Chemists have well realized the impressive stereospecificity over many thermally accessible cycloaddition with chiral catalysts, but making light work in the enantiomer control of diarylethene photocyclization has proved to be more challenging. Here, we report a unique sterically hindered diarylethene (BBTE) system with absolute enantiospecific photocyclization and cycloreversion. Moreover, we have fully separated all the five thermally stable isomers, consisting of one achiral parallel conformer, one pair of anti-parallel ring-open enantiomers, and another pair of ring-closed enantiomers, whose absolute chiral configurations are entirely elucidated by single X-ray crystallographic analyses. The photo-responsive feature exhibits a reversible, complete enantio-control transformation without racemism, offering an unrivaled unimolecular enantiospecific platform for potential applications as bistable chiroptical switches and all-photonic photomemories with optical rotation as non-destructive readout.
