“…[34] Transition-metal σ-alkynyl complexes have also found application as building blocks for the assembly of larger molecular structures and polymetallic complexes, and as functional materials with redox-switchable magnetic, [35] optical and non-linear optical response. [36,37] In this contribution we survey the nature of the redox processes associated with metal σ-alkynyl complexes and selected closely related systems, with particular emphasis on the chemical consequences of the change in molecular redox state.…”

Transition-metal σ-alkynyl complexes are valuable functional materials that have found application as sructural units in the assembly of polymetallic arrays and large molecular structures, reagents for the transfer, oligomerisation or functionalisation of alkynes, magnetic or optical materials and putative components for use in a future molecular-based electronics platform. Many σ-alkynyl complexes are redoxactive, undergoing facile oxidation (reduction) at moderate potentials to generate radical cations (anions) in which the

“…However, studies of the third-order nonlinear optical (NLO) properties of CPs are limited. NLO materials have found applications in the fields of data storage, optical computing, image transmission, optical switching and optical limiting (OL) [10][11][12]. It is a great challenge for materials scientists to develop materials with large NLO responses.…”

Four transition metal complexes have been synthesized via hydrothermal reactions, namely, [Zn(1,3-BIB)(CH 3 COO) 2 ] 2 1, [Cu 2 (1,4-BIB) 3 (CO 3 ) 2 ](1,4-BIB)Á 10H 2 O 2, {[Mn(H 2 O) 2 (1,2-BIB) 2 ]Cl 2 } n 3, and {[Mn(1,2-BIB)(1,4-NDC)] 2 } n 4, where 1,n-BIB = 1,n-bis(imidazoll-yl-methyl)benzene, n = 2, 3, 4 and 1,4-NDC = naphthalene-1,4-dicarboxylic acid. Complex 1 presents a discrete ring-like structure. Complex 2 shows a ladder-like chain structure, while complex 3 has a joint-like chain structure. Complex 4 features a layer structure constructed from [Mn 2 (N 4 O 8 )] clusters. The third-order nonlinear optical (NLO) properties of these complexes in thin films have been investigated by employing the Z-scan technique. Complexes 1-3 exhibit strong third-order NLO reversesaturable absorption, while 4 shows third-order NLO saturable absorption and a strong self-defocusing effect. The third-order NLO susceptibilities v (3) of the four complexes were calculated as 2.74 9 10 -9 , 12.24 9 10 -9 , 42.78 9 10 -9 and 189.32 9 10 -9 esu, respectively. The electronic structures of the complexes were investigated by density functional theory, and the origins of their NLO properties are discussed.

“…These advantageous characteristics are the key elements in the design of organic molecules for optical applications. Some acetylene-connected ferrocene derivatives with charge transfer ability, special redox behavior, electronic properties, and non-linear optical (NLO) properties have been reported [11][12][13][14][15][16][17].…”
