“…This choice makes it possible to investigate the Ru-NO bond in different configurational situations (more or less favorable). 37,39,74,100 it can be observed that the GS bond lengths and angles are fairly well reproduced ( Table 1). The shortening of Ru-N bond distance in GS of complex 1 when compared to those of the complexes 2-9 indicates stronger chemical bonds for ruthenium nitrosyls with cyclic amines.…”

2012The nature of Ru-NO bonds in ruthenium tetraazamacrocycle nitrosyl complexes-a computational study DALTON TRANSACTIONS, CAMBRIDGE, v. 41, n. 24, Ruthenium complexes including nitrosyl or nitrite complexes are particularly interesting because they can not only scavenge but also release nitric oxide in a controlled manner, regulating the NO-level in vivo.The judicious choice of ligands attached to the [RuNO] core has been shown to be a suitable strategy to modulate NO reactivity in these complexes. In order to understand the influence of different equatorial ligands on the electronic structure of the Ru-NO chemical bonding, and thus on the reactivity of the coordinated NO, we propose an investigation of the nature of the Ru-NO chemical bond by means of energy decomposition analysis (EDA), considering tetraamine and tetraazamacrocycles as equatorial ligands, prior to and after the reduction of the {RuNO} 6 moiety by one electron. This investigation provides a deep insight into the Ru-NO bonding situation, which is fundamental in designing new ruthenium nitrosyl complexes with potential biological applications.

“…The sensitive spectral range reaches from the near ultraviolet to the near infrared and can equally be selected by choosing appropriate compounds. [12,[20][21][22] Note that the photorefractive response is large, for example, up to Dn ≈ 10 -2 in SNP. [18] [14] we can estimate the refractive index change of the former ones to Dn ≈ 10 -3 -10 -4…”

Photoinduced Nitrosyl Linkage Isomers Uncover a Variety of Unconventional Photorefractive Media

et al. 2007

The ongoing search for new photorefractive materials offering a high photosensitive flexibility is triggered by the limited tuning ability of conventional photorefractive materials, such as electro-optic crystals, photopolymers, or liquid crystals. One of the latest discovered photorefractive materials is Na 2 [Fe(CN) 5 NO] · 2H 2 O, in which metastable linkage isomers of the nitrosyl group can be generated by light irradiation resulting in huge changes of the refractive index up to Dn ∼ 10 -2 .Here we show that this type of photorefraction is a general property arising from the generation of linkage isomers and can thus be found in many compounds containing [ML 5 NO] m± complexes, where M is a transition metal, L a ligand, and m the formal charge of the anion/cation. The benefit of this generality is reflected in the tailoring properties of the photorefractive response such as the spectral sensitivity simply by selecting different representatives of the [ML 5 NO] m± compounds.Conventional photorefractive materials, [1] where the lightinduced modulation of the refractive index is caused by the linear electro-optic effect (Pockels effect), are widely applied in nonlinear optics.[2] They feature reversible photorefractivity without chemical processing allowing for dynamical holography, [3] and the kinetics of hologram formation is described by the well-known Kiev equations. [4] In recent years a second class of reversible photorefractive media for dynamical holography has been established, the unconventional photorefractive materials. Here an optical bistability is at the origin of photorefraction and the kinetics show a characteristic transient behavior.[5] The unique properties of this class were com-
