With the rapid development of modern electronic technology, the demand for the fundamental electronic devices of logic gate circuits has been growing increasingly in the past decades. Metallo-organic compounds with unique chemical structures and optical and electronic properties are an important type of organic semiconducting material for logic gate circuits. On the one hand, the excellent optoelectronic response characteristic of metalloorganic compounds allows them to achieve elementary logic functions. On the other hand, the structural diversity and adjustability of metallo-organic compounds could be utilized for simulating versatile high-speed, low-power logic operations by different types of stimuli. Up to now, various metalloorganic compounds such as metal complexes, organic−inorganic hybrid perovskites, and MOFs materials have been explored and applied in logic gate circuits with attractive application potentials in fields of wearable electronics, sensors, and artificial intelligence (AI), etc. In this review, we first introduce the basic concepts and classification of logic gate circuits and then focus on analyzing the application principles and advantages of metallo-organic compounds including metal complexes, organic−inorganic hybrid perovskites, and MOFs materials in logic gate circuits. Finally, we outline recent specific application cases of the above materials in logic gate circuits, demonstrating their potential in the design of high-performance logic gate circuits, and summarize their challenges and future development trends. This review aims to provide a comprehensive overview of the research and application of metallo-organic compounds in the field of logic gate circuits.

“…In addition, organic materials offer numerous advantages over inorganic materials, such as high laser damage thresholds, high NLO susceptibilities, reduced dielectric constants, a wide transparency range, ultrafast response times and easier processing in the front line of NLO research [24,25]. In the same vein, some small organic compounds can also be used as models for the design of supramolecular systems, molecular logic gates, controllable switches and sensors, as well as in nanotechnology and signal processing [5,[26][27][28].…”

Using density functional theory, we have studied the intrinsic properties of styrene. First, we determine the optimized structures, structural parameters and thermodynamic properties to make our simulations more realistic to experimental results and check the stability. Second, we investigate optoelectronic, electronic and global descriptors, transport properties of holes and electrons, natural bond orbital analysis, absorption and fluorescence properties. Finally, we study nonlinear optical (NLO) properties: first- and second-order hyperpolarizability, second and third-order optical susceptibilities, hyper-Rayleigh scattering hyperpolarizability, electro-optical Pockel effect, direct current Kerr effects and quadratic refractive index. The bandgap energy E g = 5.146 eV and dielectric constant ε r = 3.062 show that styrene is a good insulator with an average electric field value of 4.43 × 10 8 Vm −1 . Thermodynamic findings show that our molecule is thermodynamically and chemically stable. Electron and hole reorganization energies of 0.393 and 0.295 eV, respectively, show that styrene is more favourable to hole transport than electron transport. Styrene is transparent with linear refractive index n = 1.750 and quadratic n 2 = 1.748 × 10 −20 m 2 W −1 . At the NLO, styrene has a non-zero value of β H R S , which confirms the existence of first-order NLO activity. Globally the study shows that the styrene monomer is suitable for the architecture design of new polymer materials for NLO applications and optoelectronic by functionalization.

“…Since the first report by de Silva et al [27], the field of molecular logic gates has advanced considerably. All possible logic gates were achieved at the molecular level, and a series of synthetic molecules and biomolecules have been utilized in the molecular computation, including proteins, enzymes, DNA, and RNA [28][29][30][31][32][33][34][35][36]. In addition, examples of more complicated logic circuits performing arithmetic functions [37,38], simple games such as Tic-Tac-Toe [39,40], and molecular scale anticancer terminator automaton [41,42] were reported.…”

The rapid progress in the field of fluorescent probes and fluorescent sensing material extended this research area toward more complex molecular logic gates capable of carrying out a variety of sensing functions simultaneously. These molecules are able to calculate a composite result in which the analysis is not performed by a man but by the molecular device itself. Since the first report by de Silva of AND molecular logic gate, all possible logic gates have been achieved at the molecular level, and currently, utilization of more complicated molecular logic circuits is a major task in this field. Comparison between two digits is the simplest logic operation, which could be realized with the simplest logic circuit. That is why the right understanding of the applied principles during the implementation of molecular digital comparators could play a critical role in obtaining logic circuits that are more complicated. Herein, all possible ways for the construction of comparators on the molecular level were discussed, and recent achievements connected with these devices were presented.
