Isoreticular Tp*–W–Cu–S cluster-based one-dimensional coordination polymers with an uncommon [Tp*WS₃Cu₂] + [Cu] combination and their third-order nonlinear optical properties

Abstract

Three isoreticular W/Cu/S 1D coordination polymers show good third-order NLO performance.

Two-dimensional Cd3-based metal–organic frameworks with halogen bonding sites for the uptake of I2

“…The presence of –CN in MOFs 3 and 4 was confirmed by the presence of absorptions at 2235 cm −1 ( 3 ) and 2237 cm −1 ( 4 ). 24…”

Butterfly and Nest‐Shaped Tp*‐W‐Cu‐S Cluster Monomers and Dimers with Hexamethylenetetramine as Ligand: Anion‐Dependent Structures and Nonlinear Optical Properties

“…[ 48 ] These values are similar to those of [(Tp*WS 3 Cu 2 Cl) 2 (dppe)] (4.71 × 10 −30 esu; dppe = 1,2‐bis‐(diphenylphosphino)ethane) [ 18 ] and [Tp*WS 3 Cu 2 (CN) 2 Cu](pz) 0.5 (3.69 × 10 −30 esu; pz = pyrazine). [ 16 ] They are slightly lower than those of [(Cp*MoS 3 Cu 3 ) 2 (bpe) 2 Br 4 ] (4.29 × 10 −29 esu; bpe = 1,2‐bis(4‐pyridyl)ethane) [ 8 ] and [Cp*MoS 3 Cu 3 (pyz)(NCS) 2 ] (2.96 × 10 −29 esu; pyz = 1,4‐pyrazine). [ 7 ] It is worth noting that the γ value is several magnitudes higher than that of 1 (1.07 × 10 −32 esu).…”

“…Transition metal clusters of organo‐thiometallates such as [Cp*MS 3 ] − (Cp* = pentamethylcyclopentadienyl; M = Mo, W), [ 1 ] [TpMoS(S 4 )] − , [Tp*MoS(S 4 )] − , [TpWS 3 ] − and [Tp*WS 3 ] − (Tp = hydridotris(pyrazol‐1‐yl)borate; Tp* = hydridotris(3,5‐dimethylpyrazol‐ 1‐yl)borate) [ 2 ] have been extensively investigated in the last two decades because of their diverse structural characteristics, [ 3‐9 ] their revelation to biological systems, [ 10‐13 ] catalysis, [ 14‐15 ] and optoelectronic materials. [ 3,16‐24 ] In this regard, we and others have developed a keen interest in the development of molecular arrays from preformed Mo(W)‐Cu(Ag)‐S clusters. [ 25‐29 ] Some of these molecular entities are capable of gas adsorption, [ 30 ] sensing, [ 31 ] or exhibit nonlinear optical properties.…”

A Cut-to-Link Strategy for Cubane-Based Heterometallic Sulfide Clusters with Giant Third-Order Nonlinear Optical Response

“…Among them, compounds 3 and 4 with 17 and 23 metal centers, respectively, are rare examples possessing a number of Cu–S interactions and π-based ligands at the molecular level. Based on previous research on coordination polymers and low-nuclearity clusters consisting of similar components, , good third-order NLO properties could be expected. Therefore, thin-film materials containing 3 and 4 were prepared for NLO measurement.…”
