“…Our group has described the fabrication of a variety of materials, such as carbon nanotubes on organic polymer substrates [10,11] or on activated carbon fibers (ACFs) [12], Cr nanowires [13], zinc oxide nanostructures [14], and zinc aluminum layered double hydroxide nanoplates [15], by applying microwave radiation to vapor-solid reactants or solutions. Microwave heating is a promising preparation method that may resolve the problems arising from conventional synthesis methods [16][17][18].…”

Fullerenes Under Microwave Irradiation IntroductionSince Krätschmer and co-workers discovered a procedure for the preparation of bulk quantities of C 60 [1] in the early 1990s, the physical properties of fullerenes have been intensively investigated. However, members of this new family of compounds are insoluble or sparingly soluble in most solvents [2] and, consequently, C 60 is difficult to handle. Chemical functionalization allows the preparation of soluble C 60 derivatives that maintain the electronic properties of fullerenes. For this reason, the chemistry and derivatization of fullerenes has continued to attract attention aimed at preparing derivatives with interesting physical properties and biological activities [3]. New materials based on C 60 derivatives have shown promise in the fields of material science [4], solar energy conversion [5], nonlinear optical behavior [6], superconductivity [7], ferromagnetism [8], medicinal chemistry [9], and HIV-1 protease inhibition [10].Among the suitable procedures for the functionalization of fullerenes (Scheme 23.1) [11], cycloadditions provide a powerful tool as C 60 behaves as an electron-deficient olefin with a relatively low-lying LUMO (−3.14 eV) [12,13].As a consequence, a large variety of cycloaddition reactions have been carried out [12, 14] in which C 60 (1) is the reactive 2π component. In this context, [1 + 2]-, [2 + 2]-, [3 + 2]-, and [4 + 2]-cycloadditions have all been performed (Scheme 23.2) and the conditions for cycloadduct formation depend strongly on the gap between the controlling orbitals. For this reason, it is frequently necessary to use harsh conditions involving several hours (or days) under reflux in high-boiling solvents. As microwave irradiation has been successfully used in cycloaddition reactions solving problems concerning reversibility and decomposition of reagents and/or products, it was evident to use this methodology in fullerene chemistry as most fullerene derivatives are prepared by Diels-Alder [15] or 1,3-dipolar cycloaddition reactions [16].Microwaves in Organic Synthesis, Third Edition.

Emissive organometallic polymers are an important class of functional materials characterized by the combined photoluminescent features of organometallic molecules and the properties of traditional polymers. In this work, the emissive organometallic complex, [CuBr(PPh ) (4-methylpyridine)], is successfully, mechanically ground into a random copolymer built on 4-(diphenylphosphino)styrene (DPVP) and n-butyl acrylate (BA) monomers. The resultant hybrid materials successfully inherit the emissive centers, and are significantly reinforced by the copper complexes as chemical crosslinkers in the polymeric continuum. These organometallic polymers are also proved to have excellent vapoluminescent properties, exhibiting unique responses to many organic solvent vapors, reflecting their rapid loss and recovery of photoluminescence. Mechanically robust and flexible films prepared with these organometallic Cu(I)-polymers are tested as recoverable sensors for hazardous volatile chemical compounds (VOCs) such as toluene, acetone, chloroform, and dichloromethane, and the low limits of detection (LOD) can reach as low as 1 × 10 -8 × 10 mg L (0.2-3.3 ppmV, parts per million-volume) for various VOCs. This work sheds lights on the design and fabrication of organometallic polymers for advanced applications.
