“…8), and its fluorinated analogue TCPE-F (tetrakis[4-(4-carboxy-2-fluoro-phenyl)phenyl]ethylene; bpy = 4,4-bipyridine). 34 The presented MOFs in this study interestingly showed a lower TPA cross section than their corresponding ligands as solid organic acids, in contradiction to the conducted studies with TCPE so far. A detailed experimental and theoretical investigation revealed that reduced conformational locking of phenyl ring movements in the porous MOFs is responsible for the lower TPEF behavior.…”

“…The framework contraction not only improves the single-photon emission parameters, but also enhance the TPA cross section. [153] They further derived structure-property relations of the interplay between the photonic properties and the spatial arrangements of optically active chromophores within the framework.

metal chalcogenides, [17,18] graphdiyne, [19][20][21] etc.) and perovskites [22][23][24][25][26] have been in a state of vigorous development and rapid advances for applications in optoelectronics, catalysis, energy conversion, due to their autologous admirable chemistry and physics characteristics. [27,28] Porous materials, a scientifically evolving and functionally compelling class of solid compounds with well-defined pore structures, such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and polyoxometalates (POMs), have attracted broad research interest because of their wide applications in many fields including, but not limited to, adsorption, separation, catalysis, and photovoltaics. [29][30][31][32] Through fine control over the organic units to create predesigned skeletons, an exceptionally large set of materials with unique porous structures and remarkable properties have been developed. [33,34] MOFs, also known as coordination polymers or coordination networks, are one class of crystalline porous materials prepared by the self-assembly of metal ions or clusters with organic ligands. [35] They have drawn tremendous research interest for their customizable chemical structures along with unique chemical and physical properties, [36][37][38][39][40][41] which guarantee their wide applications as adsorption and separation, catalysts, magnetic, and light emitting materials. [36,[42][43][44][45] The use of appropriate ligands with optimized electronic push-pull structures, the degree of conjugation in the system and the encapsulation of guest molecules with different properties are some of the effective strategies to enhance the linear and nonlinear optical properties of the MOFs materials. [46][47][48] COFs, constructed from organic moltifs linking through strong covalent bonding, are a kind of crystalline porous materials in which the atoms of organic units are precisely integrated to create periodic frameworks and nanopores. [49,50] Although the thermal stability and crystallinity of COFs are lower than MOFs, they have received wide attention due to their low density, large surface area and strong ππ stacking. [51][52][53][54] It has been appreciated that the applications of COFs materials in third-order NLO such as two-photon fluorescence have been well developed in recent years. [55][56][57] Similar to MOFs and COFs, POMs formed by the coordination of early transition metals and oxygen atoms are a class of crystalline porous materials with unique structures and properties for their exceptional crystallinity and high stability. [58] POMs are intrinsically electron deficient, and their electronaccepting capability in combination with highly delocalized π-conjugated systems is particularly promising for producing NLO materials. [59,60] The structure of all the crystalline porous Crystalline porous materials have been extensively explored for wide applications in many fields including nonlinear optics (NLO) for frequency doubling, two-photon absorption/emission, optical limiting effect,...

“…A recent contribution investigated origins of disparate spectrally-resolved 2PA properties of fluorinated and non-fluorinated pillar-layered MOFs and their corresponding ligands. [31] The MOFs had generic formulas of [Zn 2 (TCPE)(bpy)] (1) and [Zn 2 (TCPE-F)(bpy)] (1-F) where TCPE is the same tetraphenylethene-based ligand as in previous sections, while TCPE-F, tetrakis[4-(4-carboxy-2-fluoro-phenyl)phenyl]ethylene, is a tetrafluorinated analogue of TCPE. 2PA cross-sections have been determined with the use of SSTPEF technique in 650-950 nm spectral range.…”

The activity in the research on novel optical materials exhibiting nonlinear optical (NLO) properties is surveyed, especially nonlinear absorption, that may be attractive for various applications, including those in optoelectronics, photonics, and biophotonics. The recently introduced concept of “NLO pigments”—insoluble colored materials that can exhibit useful NLO effects—is demonstrated to apply to the multifunctional group of coordination polymers (CPs) and their subgroup of metal‐organic frameworks (MOFs), which may be applied in their microcrystalline form or as nanoparticles. Nanocrystalline materials such as semiconductor quantum dots or plasmonic particles made of noble metals have been widely studied and their properties have been often reviewed, thus they are not included in this review. On the other hand, studies performed on perovskites are described: materials that appear to have great potential for NLO applications in addition to their well‐known merit in photovoltaics. There is also much activity in the field of low‐dimensional, especially 2D structures of various kinds, and this review covers many examples of such structures, not including the broad topic of carbon nanostructures (graphene, nanotubes etc.) but concentrating on other emerging nonlinear optical materials such as black phosphorus, transition metal dichalcogenides, MXenes, and topological insulators.
