“…We propose a photoswitchable molecular system that also demonstrates photoswitchable light emission. [38][39][40][41][42][43][44][45][46][47][48] External irradiation λ ex would be absorbed and re-emitted by each species with an emission spectrum that is preferentially re-absorbed by the other isomer. A schematic example of this feedback concept is shown in Figure 1 for two dye functionalities substituted onto an E/Z photoswitch core 49 in which E → Z photoisomerization leads to red-shifted excimer emission.…”

A chemical system is proposed that is capable of amplifying small optical inputs into large changes in internal composition, based on a feedback interaction between switchable fluorescence and visible-light photoswitching. This system would demonstrate bifurcating reaction kinetics under irradiation and reach one of two stable photostationary states depending on the initial composition of the system. This behavior would allow the system to act as a chemical realization of the flip-flop circuit, the fundamental element in sequential logic and binary memory storage. We use detailed numerical modeling to demonstrate the feasibility of the proposed behavior based on known molecular phenomena, and comment on some of the conditions required to realize this system.

“…[1][2][3][4][5][6][7] In recent years, fluorescent switches based on diarylethene, spiropyran (SP), and fulgide (FUL), as well as their derivatives, have been reported. [8][9][10][11][12][13][14][15][16][17][18][19][20] However, most of the reported fluorescent switches were realized in solution.

Solid-state fluorescent switches with reversible luminescence characteristics have attracted considerable attention because of their broad applications in advanced photonics, such as anticounterfeiting inks, optical writing and erasing, and biological imaging. Herein, we have fabricated a solid-state reversible fluorescent switch under alternating UV (365 nm) and visible light treatments based on a fulgide (FUL)-functionalized tetraphenylethylene (TPE) derivative (TPE-FUL) containing a photochromic group FUL and aggregation-induced emission (AIE) luminogen TPE. TPE-FUL exhibited excellent reversible absorption and luminescence owing to the interconversion between open TPE-FUL (O-TPE-FUL) and closed TPE-FUL (C-TPE-FUL). Photophysical and theoretical investigations revealed that the luminescence of O-TPE-FUL is based on the local excited state of the TPE moiety, whereas the fluorescence quenching of C-TPE-FUL originates from the intramolecular charge transfer from the TPE to the FUL moiety. The excellent reversible photoswitching properties of TPE-FUL in the solid state allows for its potential use in advanced optical memory applications, such as anticounterfeiting, optical writing and erasing, and information encryption.
