This work is an important contribution to the development of neuromorphic engineering based on solutions of nonlinear chemical systems. It reports the results of experiments and simulations regarding the optical communication between the Belousov-Zhabotinsky reaction and photochromic and luminescent materials. It demonstrates that thermally reversible photochromic and luminescent compounds are dynamic models of phasic photo-excitable neurons. Moreover, it shows that photoreversible photochromic compounds can be used for the implementation of optical synapsis and memory effects. Finally, it reports the first example of transmission of a chaotic signal between a Hydrodynamic Photochemical Oscillator based on a photochromic naphthopyran and a luminescent acridinium salt.

One is neuromorphic computing, which consistso fd evising surrogates of neurons for brainlike computers by using conventional passive and activec ircuit elements, [6] two-terminal devices with an onvolatile adjustable internal state such as memristive components, [7] or oscillatory and excitable chemical reactions.…”

This work demonstrates the computational power of a hydrodynamic photochemical oscillator based on a photochromic naphthopyran generating aperiodic time series. The chaotic character of the time series is tested by calculating its largest Lyapunov exponent and the correlation dimension of its attractor after building its phase space through the Takens' theorem. Then, the chaotic dynamic is shown to be suitable to implement all the fundamental Boolean two-inputs-one-output logic gates. Finally, the strategy to implement fuzzy logic systems (FLSs) based on the time series is described. Such FLSs promise to be useful in the field of computational linguistics, which is concerned with the development of artificial intelligent systems able to transform collections of numerical data into natural language texts.

“…Enormous efforts had recently been devoted to develop artificial intelligence with vague and incomplete information. But only a few FIS-superimposed infinite-valued molecular logic systems have been reported to date [7,[64][65][66][67][68][69][70][71]. Moreover, to the best of our knowledge, there is no report on Fuzzy logic system (FLS) based on Ru(II) complex with excellent photophysical properties in the visible region.…”

“…But in most of the practical systems, there are some intermediate states which lie in between. The Fuzzy logic system (FLS) is thought to be a potential alternative of Boolean logic to characterize the intermediate values between completely true (1) and completely false (0) [7,[64][65][66][67][68][69][70][71]. The motivation behind developing the FLS is based on the notion that human reasoning and decision making process is too complex to be precisely defined and believed to act as automatic fine-tuning control systems that can handle several middle steps with varying degrees of truth.…”
