“…The use of molecules—particularly in reversible reactions such as Belousov–Zhabotinsky type or interactions found in appropriately modified DNA—for the construction of fuzzy logic systems has been presented in the works of Gentili, Deaton, Kjems, and others. It has also been discussed in our articles . This kind of approach, especially when combined with some aspects of neuromimetic computation (e.g.…”

Titanium dioxide nanocomposites were synthesized in hierarchical architectures through the use of a 1,4‐dihydroxyanthraquinone photosensitizer. In the first step, the dye was either incorporated into the TiO2 core or adsorbed on its surface. In the subsequent phase, both structures were covered with an outer layer of titanium dioxide. The structure, morphology, aggregation, spectroscopic, and electrochemical properties of the synthesized TiO2‐based materials are presented with emphasis on the photosensitization and the photocurrent switching phenomena, which are also discussed within the context of the optical logic gates implementation and fuzzy logic systems operation. We present three different interpretations of the photocurrent action spectra yielding binary, ternary, or fuzzy logic circuits.

“…Numerous articles have been published on this topic and various phenomena have been already discussed-particularly, processes influencing the intensity and polarity of photocurrents have been presented on numerous occasions [2][3][4] . We also have contributed to this field and explained how the electrical response to the irradiation may be tuned in nanocomposites and how the output of a simple optoelectronic device made of hybrid materials could be treated in terms of information theory [5][6][7] .…”

Light intensity-induced photocurrent switching effect

A better control over processes responsible for the photocurrent generation in semiconductors and nanocomposites is essential in the fabrication of photovoltaic devices, efficient photocatalysts and optoelectronic elements. Therefore, new approaches towards photochemical properties tuning are intensively searched for. Among numerous parameters, the photocurrent polarity is of great importance to the overall performance of a device. Usually, the polarity is controlled through an alignment of electronic states/bands, tailoring of applied potential or suitable selection of incident light wavelengths. In most scenarios though, the influence of light intensity is somehow neglected and either some arbitrarily chosen, natural conditions are mimicked or this parameter is varied only in a narrow range. Here we present a ternary nanocomposite in which the persistent photocurrent polarity switching is achieved through changes in the light intensity. We also present arguments suggesting this behaviour is of a general character and should be considered also in other photochemical systems.

Phototherapeutic applications of carbon monoxide (CO)‐releasing molecules are limited because they require harmful UV and blue light for activation. We describe two‐photon excitation with NIR light (800 nm)‐induced CO‐release from two MnI tricarbonyl complexes bearing 1,8‐naphthalimide units (1, 2). Complex 2 behaves as a logic OR gate in solution, nonwovens, and in HeLa cells. CO release, indicated by fluorescence enhancement, was detected in solution, nonwoven, and HeLa cells by single‐ (405 nm) and two‐photon (800 nm) excitation. The photophysical properties of 1 and 2 have been measured and supported by DFT and TDDFT quantum chemical calculations. Both photoCORMs are stable in the dark in solution and noncytotoxic, leading to promising applications as phototherapeutics with NIR light.
