“…For these studies, nonaqueous solutions are of particular interest because up to now most of the laser-induced metal deposition experiments were performed in aqueous media. 1 Copper(II) complexes are labile, and therefore, they have been used as model systems to study the dynamics of the ligand exchange mechanism. 2−5 Also, copper plays a significant role in the metabolism of the human's body.…”

Photochemistry of copper(II) monochlorocomplexes in methanol and acetonitrile solutions is studied by UV-pump/broadband deep-UV-to-near-IR probe femtosecond transient absorption spectroscopy. Upon 255 and 266 nm excitation, the complexes in acetonitrile and methanol, respectively, are promoted to the excited ligand-to-metal charge transfer (LMCT) state, which has a short (sub-250 fs) lifetime. From the LMCT state, the complexes decay via internal conversion to lower-lying ligand field (LF) d−d excited states or the vibrationally hot ground electronic state. A minor fraction of the excited complexes relaxes to the LF electronic excited states, which are relatively long-lived with lifetimes >1 ns. Also, in methanol solutions, about 3% of the LMCT-excited copper(II) monochlorocomplexes dissociate forming copper(I) solvatocomplexes and chlorine atoms, which then further react forming long-lived photoproducts. In acetonitrile, about 50% of the LMCT-excited copper(II) monochlorocomplexes dissociate forming radical and ionic products in a ratio of 3:2. Another minor process observed following excitation only in methanol solutions is the re-equilibration between several forms of the copper(II) ground-state complexes present in solutions. This re-equilibration occurs on a time scale from sub-nanoseconds to nanoseconds.

“…Thus, the implementation of the aforementioned solutions in LCLD experiments allowed to produce copper structures with good topology and high electrical conductivity properties, as a result, the compositions of these solutions were chosen for further studies. It is known that the LCLD mechanism is still under debate and not completely clear [1][2][3][4][5]. In order to shed light on this problem one should know how metal is reduced during the laser-induced chemical deposition process.…”

“…Here, we propose to use of laser induced chemical liquid-phase deposition (LCLD) for the aforementioned purposes. In general, LCLD is a technique dealing with a treatment of a local region of the dielectric substrate or conductor on air or under a layer of liquid solution (plating solution) by a focused laser beam [1][2][3][4][10][11][12]. In turn, laser irradiation of the plating solution leads to the acceleration of metal reduction reaction in the irradiated area as a result of the temperature increase in the local volume of solution within the focus of the laser beam.…”

Furthermore, the versatility of the LCLD method is that the chemical and physical parameters for the efficient metal deposition can be adjusted to any substrate surface or the reaction mixture.…”

The method of laser-induced chemical deposition of metal from solution was applied in the continuous in situ laser generation of metal copper catalysts for model organic synthesis reactions. The gas phase products producing during laser-induced copper deposition were analyzed by gas mass spectroscopy whereas solutions used for the copper deposition were investigated before and after laser irradiation using chromato-mass and NMR spectroscopy. It was found out that the catalysis of the studied organic reactions by metal catalysts generated during laser deposition process occurs only upon laser irradiation of the reaction mixture, in turn, the copper structures deposited under laser light exhibit no catalytic activity.Keywords: laser-induced metal deposition, catalysis, copper, gas mass spectroscopy Introduction.One of the most important scientific and engineering tasks is the development of new types of catalysts for selective organic synthesis. Among them are easily renewable and adaptable for flow-through reactors heterogeneous catalysts which provide advantages compared to homogeneous catalysis. It is known that the nanostructured and highly porous materials with a large specific surface area exhibit the highest catalytic activity. Therefore, the development of novel catalytic systems for the organic reactions catalyzed by metal nanosructures is an actual problem of modern chemistry. As a rule, for that purpose the expensive metals such as gold, platinum, palladium, etc are used. On the other hand, the use of cheaper metals such as copper, cobalt, zinc, etc results in fast "contamination" of the catalyst surface by reaction products and the loss of activity. In addition, regeneration of waste catalysts and the synthesis of new is time consuming and quite expensive process.The technique used in this work provides the in situ catalyst generation and in which the problem with activation of the catalyst surface is diminished by constant replacement of the contaminated during the generation process catalyst by new one. In this approach, nano-sized metal particles generated upon laser irradiation are involved in the catalysis process then these particles are deposited forming the pure metal structures suitable for further usage or regeneration. Here, we propose to use of laser induced chemical liquid-phase deposition (LCLD) for the aforementioned purposes.
