    The Eternal Quest for Practical Low Bandgap Polymers
    Seth C. Rasmussen, Spencer J. Gilman, Wyatt D. Wilcox
    General Chemistry. 2023, 9 (1-2): 220010-220010.   DOI: 10.21127/yaoyigc20220010
    Abstract   PDF (756KB) ( )
    The bandgap (Eg) of conjugated materials effects a variety of critical properties such that efforts to control the bandgap have become a basic tenet in the design of conjugated polymers. One goal of such efforts is to minimize the Eg with the goal of producing technologically useful low bandgap (Eg < 1.5 eV) polymers. This perspective will introduce the two primary approaches to low Eg polymers (i.e., quinoidal systems and donor-acceptor frameworks) and discuss important new directions for both design principles.

    On the Ground State Structures of Bimetallic NimCun (m + n ≤ 6) Clusters and Their Reactivity toward O2
    Heriberto Cruz-Martínez, Eduardo A. Ortiz-Vázquez, Hugo Rojas-Chávez, Patrizia Calaminici
    General Chemistry. 2023, 9 (1-2): 220012-220012.   DOI: 10.21127/yaoyigc20220012
    Abstract   PDF (981KB) ( )
    Extensive auxiliary density functional theory (ADFT) computations were performed to study the most stable structures, stabilities and chemical reactivity toward O2 of bimetallic NimCun (m + n ≤ 6) clusters. The shape of the most stable structures changes as the number of Ni and Cu atoms of the system under study increases with a consequent change of the energy, magnetic and reactivity properties. All obtained minimum-energy structures for these bimetallic systems composed with three and four atoms possess triangular and rhombic structures, respectively. According to our computations, the most stable structures for Ni4Cu, Ni3Cu2, and Ni2Cu3 clusters are trigonal-bipyramidal, while, for the NiCu4 cluster, two structures were identified as the most stable (with planar and trigonal-bipyramidal structures, respectively). The most stable structure for the Ni5Cu cluster is octahedral, while for the Ni4Cu2, Ni3Cu3, Ni2Cu4, and NiCu5 clusters, an incomplete pentagonal bipyramid was found as the ground-state structure. For all cluster sizes, as the number of Cu atoms in the system increases, the magnetic moment per atom tended to decrease. The O2 adsorption on bimetallic NimCun (m + n = 6) clusters is more favored when O2 binds by a bridge-type bond. Moreover, our computations indicate that O2 is preferentially adsorbed on the Ni atoms of bimetallic NimCun (m + n = 6) clusters.

    Synthesis, DMF Sensing and Proton Conduction of a Two-Dimensional Metal-Organic Framework
    Datang Chen, Weiming Liao, Jun He
    General Chemistry. 2023, 9 (1-2): 230003-230003.   DOI: 10.21127/yaoyigc20230003
    Abstract   PDF (791KB) ( )
    A two-dimensional layered metal-organic framework, [Eu(C26H15NO4)Cl]n (EuCDDB), was synthesized by the reaction of EuCl3·6H2O and 4,4'-(9H-carbazole-3,6-diyl)dibenzoic acid (H2CDDB) through one-pot solvothermal process, and characterized by several technologies of single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis, and Fourier transform infrared spectrum. The crystal structure reveals that hydrogen bonding interaction happens between NH groups and coordinated chloride ions from the adjacent coordination layers, meanwhile, well-opened one-dimensional channel allows the accommodation of water molecules. These characteristics endow EuCDDB with a considerable proton conductivity of 3.70 × 10-6 S cm-1 under 90 °C and relative humidity of 90%. In addition, EuCDDB also exhibits turn-on luminescent sensing on DMF molecules by enhanced Eu3+ red emission resulting from efficient ligand-to-metal energy transfer process.

    Comparative Analysis of AquaSun Sol-Gel Coating and Commercial Antifouling Paint in Protecting Shipbuilding Steel in Port Seawaters
    Rosaria Ciriminna, Salvatore Vacante, Antonino Scurria, Gabriella Di Carlo, Mario Pagliaro, Annamaria Visco
    General Chemistry. 2023, 9 (1-2): 230001-230001.   DOI: 10.21127/yaoyigc20230001
    Abstract   PDF (500KB) ( )
    The results of the first tests aimed to assess antifouling activity of new AquaSun sol-gel paint coated on shipbuilding steel immersed in highly polluted port seawaters, compared to a state-of-the-art self-polishing commercial silyl acrylate antifouling topcoat containing high amounts of cuprous oxide and copper pyrithione, are promising.
