“…Smart filters can save time and resources by providing efficient purification for nanoparticle synthesis. Apart from mechanical work, light can trigger several other functions, such as photoluminescence [202,203], photochromism [204,205], photoreactivity [206], and photoconductivity [207,208]. These responses are advantageous for the design of 2D systems or hybrid systems that can be incorporated into intelligent devices.…”

Two-dimensional and pseudo-2D systems come in various forms. Membranes separating protocells from the environment were necessary for life to occur. Later, compartmentalization allowed for the development of more complex cellular structures. Nowadays, 2D materials (e.g., graphene, molybdenum disulfide) are revolutionizing the smart materials industry. Surface engineering allows for novel functionalities, as only a limited number of bulk materials have the desired surface properties. This is realized via physical treatment (e.g., plasma treatment, rubbing), chemical modifications, thin film deposition (using both chemical and physical methods), doping and formulation of composites, or coating. However, artificial systems are usually static. Nature creates dynamic and responsive structures, which facilitates the formation of complex systems. The challenge of nanotechnology, physical chemistry, and materials science is to develop artificial adaptive systems. Dynamic 2D and pseudo-2D designs are needed for future developments of life-like materials and networked chemical systems in which the sequences of the stimuli would control the consecutive stages of the given process. This is crucial to achieving versatility, improved performance, energy efficiency, and sustainability. Here, we review the advancements in studies on adaptive, responsive, dynamic, and out-of-equilibrium 2D and pseudo-2D systems composed of molecules, polymers, and nano/microparticles.

“…A completely new class of hybrid polyfunctional compounds has recently been discovered. Such compounds combine a photochromic cationic spiropyran sublattice and a magnetic anionic bimetallic oxalate sublattice [18,19], in which the spiropyran acts as a photochemical molecular switch perturbing the magnetic sublattice.…”

Syntheses are reported for cationic indoline spiropyrans with a quaternized pyridinium fragment in the aliphatic side chain, which display photochromic properties in solution. The major effect of introducing a quaternized pyridinium fragment into the benzopyran part of the spiropyran entails a significant decrease in the rate of thermal relaxation processes.Keywords: cationic indolinospiropyrans, pyridinium fragment, photochromism, electronic absorption spectroscopy.Photochromic organic molecules, some of which are spiropyrans and spirooxazines, have recently been the subject of intensive research due to the use of these compounds in optical recording and data transformation systems, sensors, optical electronics, optical bioelectronics, and transport systems [2-5].However, the limit to improving the characteristics of monofunctional materials has now been reached and attention is being directed toward the development of hybrid polyfunctional materials holding promise for application in molecular electronics.A possible solution of this problem lies in the creation of hybrid polyfunctional materials, which combine structural units responsible for different physicochemical properties such as photochromism and magnetism [6][7][8][9], photochromism and conductivity [10,11], electrical and magnetic properties [12], and optical dichroism and magnetism [13]. A systematic study of both the structure and properties of such units and the feasibility of their combination into a single crystal lattice is required for the development of such materials from molecular units differing in their chemical nature, the investigation of the interaction of such units on each other, and methods for the modification of the properties of the separate units to impart desired properties to the hybrid materials. _______ * For Communication 30 see [1]. * 2 Dedicated to Academician of the Russian Academy of Sciences B.
