“…Two nanostructured lead(II) complexes of quinolone-2-carboxylic acid 613 and 2-methyl-8-hydroxyquinoline 611 were prepared by the Davarani group using either electrochemistry or sonoelectrochemistry (Scheme ). Nanosized samples were obtained thanks to a combination of electrochemistry and powerful ultrasonic radiation (20 kHz–10 MHz).…”

Organometallic complexes: these two words jump to the mind of the chemist and are directly associated with their utility in catalysis or as a pharmaceutical. Nevertheless, to be able to use them, it is necessary to synthesize them, and it is not always a small matter. Typically, synthesis is via solution chemistry, using a roundbottom flask and a magnetic or mechanical stirrer. This review takes stock of alternative technologies currently available in laboratories that facilitate the synthesis of such complexes. We highlight five such technologies: mechanochemistry, also known as solvent-free chemistry, uses a mortar and pestle or a ball mill; microwave activation can drastically reduce reaction times; ultrasonic activation promotes chemical reactions because of cavitation phenomena; photochemistry, which uses light radiation to initiate reactions; and continuous flow chemistry, which is increasingly used to simplify scaleup. While facilitating the synthesis of organometallic compounds, these enabling technologies also allow access to compounds that cannot be obtained in any other way. This shows how the paradigm is changing and evolving toward new technologies, without necessarily abandoning the round-bottom flask. A bright future is ahead of the organometallic chemist, thanks to these novel technologies. CONTENTS1. Introduction 7530 2. Technologies 7530 2.1. Grinding and Milling 7530 2.2.

“…Coordination polymer 1 exhibits a broad, green luminescent emission band with a maximum at 511 nm (k ex = 355 nm) spreads from blue to green wavelengths (475-580 nm) and can be attributed to ligand-to-metal charge transfer (LMCT) between delocalized p bonds of the aromatic L ligands and the p orbitals of Pb(II) ions [47,48]. The novel lead(II) coordination polymer 1 may be a potential candidate for the emitting layer in organic light-emitting diodes (OLEDs) due to the broad luminescence emission peak, electron accumulation, conjugated structure, and stability under humid air and high temperature [49][50][51][52][53][54]. Compounds 468 nm (3) when the excitation wavelengths are 360, and 380 nm, respectively.…”

Treatment of N,N 0 -bis(4-pyridylmethylene)-1,5-naphthalenediamine (L) with Pb(OAc) 2 /KBr, Cu(acac) 2 , and Cu(OAc) 2 afforded three new coordination polymers [Pb(l-L)(l-Br) 2 ] n (1), [Cu(l-L)(acac) 2 ] n (2), and [Cu 2 (l-L)(l-OAc) 4 ] n (3). These coordination polymers have been structurally characterized by single crystal X-ray diffraction. Compound 1 has a 2D sheet structure in which the lead(II) centers are bridged by both L and bromide ligands. Compound 2 adopts a 1D neutral coordination chain and consists of bis (2,4-pentanedionato) copper(II) units connected by rigid bridging L ligands. The structure of compound 3 also adopts a 1D neutral coordination chain in which two copper centers are connected through four acetate groups to form a Cu(OAc) 4 Cu paddle-wheel-type cage between two bridging L ligands. The FT-IR spectra, thermal behavior and photoluminescence properties of these coordination polymers have also been investigated.

“…As we know, mechanical effects induced by ultrasonication can be very helpful for the activation of electrochemical reactions. A new lead(II) complex [Pb(mq) 2 ] (mq = 2-methyl-8-hydroxyquinoline) in the presence of the 2-methyl-8hydroxyquinoline ligand was prepared [47]. Studies based on HOMO and LUMO energy levels showed that a good level of luminescence would be sustained with this complex, indicating the complex could be used as a light emission layer in organic light-emitting diodes.…”

remove the products from the sonic probe cathode. The shape and size of the nanomaterials can be adjusted by varying the operating parameters which include the ultrasonic power, current density, deposition potential, and ultrasonic versus electrochemical pulse times as well as the pH, temperature, and composition of the electrolyte in the sonoelectrochemical cell. Moreover, another setup that is the immersion of a conventional electrochemistry cell into a fixed position in the ultrasound bath is also introduced. Herein, we summarize the recent development of sonoelectrochemical synthesis and characterization of novel nanomaterials, including metals, semiconductors, polymers, and various nanocomposites. A brief look is also taken into the future enabling developments in this field.
