“…Interest in designing high-performance nonlinear optical (NLO) materials is growing rapidly due to their widespread applications in optical computing, − optical communication, , optical switching, , optical logic functions, , dynamic image processing, , and many other optoelectronic fields. − Recently, a unique class of compounds known as electrides having isolated excess electrons has garnered great interest from the chemical society. − Due to this nontrivial electronic structure, they are easily polarizable and can serve as superior nonlinear optical materials. ,, Electrides due to their certain interesting properties such as the ultralow work function, relatively high catalytic activity, high electronic mobility, and optical and anisotropic properties have great potential for various applications. − In 1983, Dye and co-workers fabricated the first organic crystalline electride consisting of organic complexant cages in which alkali metals and electrons were trapped . Since then, various organic and inorganic electrides have been reported in literature, and their novel electronic structures have been investigated both computationally and experimentally. − …”

In this report, the geometric and electronic properties and static and dynamic hyperpolarizabilities of alkali metal-doped C6O6Li6 organometallics are analyzed via density functional theory methods. The thermal stability of the considered complexes is examined through interaction energy (E int) calculations. Doping of alkali metal derives diffuse excess electrons, which generate the electride characteristics in the respective systems (electrons@complexant, e–@M@C6O6Li6, M = Li, Na, and K). The electronic density shifting is also supported by natural bond orbital charge analysis. These electrides are further investigated for their nonlinear optical (NLO) responses through static and dynamic hyperpolarizability analyses. The potassium-doped C6O6Li6 (K@C6O6Li6) complex has high values of second- (βtot = 2.9 × 105 au) and third-order NLO responses (γtot = 1.6 × 108 au) along with a high refractive index at 1064 nm, indicating that the NLO response of the corresponding complex increases at a higher wavelength. UV–vis absorption analysis is used to confirm the electronic excitations, which occur from the metal toward C6O6Li6. We assume that these newly designed organometallic electrides can be used in optical and optoelectronic fields for achieving better second-harmonic-generation-based NLO materials.

“…Optical nanosensors are based on the interactions between analytes and light. 33,34 The most representative optical detection methods used in nano-sensors are: Surface plasmon resonance (SPR), localized surface plasmon resonance (LSPR), surface-enhanced Raman spectroscopy (SERS), fluorescent spectroscopy and colorimetry. 35 Surface plasmon resonance (SPR) sensors rely in measuring the amount of change in reflected light from a thin metal surface due to an absorbed analyte.…”

“…Nanosensors have broad applications in biology, detecting contaminated water, medicine through detecting malignant tumors and detecting microorganisms. These sensors have low-cost, fast synthesis routes and are highly sensitive and efficient [7]. Piezoelectric materials, such as piezoelectric ceramics, can convert electrical energy into mechanics and vice versa [8].…”

Materials science seeks the development of new materials with optimized characteristics. The union of various areas as chemistry, physics, nanotechnology, biology, and medicine catalyzes news materials. Smart materials react to external stimuli by modifying their chemical, mechanical, magnetic, optical, electrical, thermal properties. They have superior efficiency to the materials currently available and promise many advantages to their consumers. However, smart materials must be associated with sustainable technological progress. As a result of highly evolved technologies and intense laboratory research, their final characteristics must be connected with sustainable protocols. In addition to a significant difference associated with a wide application in various areas as textile industry, construction, medicine, drugs delivery, microorganisms’ detection, smart materials must not pollute from production to disposal, and more than that, they must seek compensation for the harmful effects of this evolution on nature. In this way, smart materials will be an excellent advantage for the future and the environment.
