Synthesis, Structure, and Electroluminescence of BR2q (R = Et, Ph, 2-Naphthyl and q = 8-Hydroxyquinolato)

Abstract: Three 8-hydroxyquinolato (q) boron compounds B(C2H5)2q (1), BPh2q (2), and B(2-naph)2q (3) have been synthesized by the reaction of 8-hydroxyquinoline with an appropriate BR3 compound. Compounds 1−3 have a tetrahedral geometry as demonstrated by the structure of 1 determined by a single-crystal X-ray diffraction analysis. Compounds 1−3 emit a green-blue color at λmax = 495−500 nm when irradiated by UV light. The electroluminescent (EL) properties of 2 and 3 were examined by fabricating EL devices using 2 and 3 as the light-emitting layer, respectively. The devices of 2 produce a yellow-green light with broad emission spectra, attributed to the formation of an exciplex of 2 with the N,N‘-di-1-naphthyl-N,N‘-diphenylbenzidine (NPB) in the hole transport layer while the intrinsic EL emission of compound 3 was observed. Both 2 and 3 were found to be good electron transport materials in EL devices.

Advances in the Synthesis of Organoborane Polymers for Optical, Electronic, and Sensory Applications

Abstract: The past decade has witnessed renewed interest and numerous unexpected discoveries in the area of main group organometallic chemistry. Unusual bonding modes have been uncovered,1-4 new materials have been developed,5,6 and new applications are being pursued.7-12 With respect to new materials with unusual properties, an exciting field is the development of hybrid polymers that combine main group elements with typical organic structures in one framework.13,14 Among main group organic-inorganic hybrid polymers, those involving Group 14 and Group 15 elements have received tremendous attention over the past several decades, with silicones, polysilanes, and polyphosphazenes among the most thoroughly studied materials.15-17 A variety of other classes of new polymers containing not only silicon and phosphorus,18-22 but also the heavier homologues, such as germanium, tin, arsenic, and antimony have been introduced more recently.23-26

Luminescent materials: locking π-conjugated and heterocyclic ligands with boron(III).

Abstract: Multidisciplinary research on novel organic luminescent dyes is propelled by potential applications in plastic electronics and biomedical sciences. The construction of sophisticated fluorescent dyes around a tetrahedral boron(III) center is a particular approach that has fueled the creativity of chemists. Success in this enterprise has been readily achieved with simple synthetic protocols, the products of which display unusual spectroscopic behavior. This account is a critical review of recent advances in the field of boron(III) complexes (excluding BODIPYs and acetylacetonate boron complexes) involving species displaying similar coordination features, and we outline their potential development in several disciplines.

A Series of Highly Connected Metal–Organic Frameworks Based on Triangular Ligands and d10 Metals: Syntheses, Structures, Photoluminescence, and Photocatalysis

Abstract: Four novel highly connected metal–organic frameworks (MOFs) based on d10 metals and triangular ligands, namely, [Ag7(4,4′-tmbpt)(HL)2(L)(H2O)] (1), [NaCd3(4,4′-tmbpt)(L)2(OH)]·H2O (2), [Cd3(3,3′-tmbpt)2(L)2(H2O)2]·3.5H2O (3), and [Cd3(3,4′-tmbpt)2(L)2(H2O)]·1.5H2O (4) (H3L = 5-(4-carboxybenzyloxy)isophthalic acid, 4,4′-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(4-pyridyl)-1,2,4-triazole, 3,3′-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(3-pyridyl)-1,2,4-triazole, and 3,4′-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3-(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole) have been synthesized under hydrothermal conditions. Compound 1 features a three-dimensional (3D) (3,12)-connected net based on heptanuclear [Ag7(COO)7] units. Compound 2 displays a 3D (3,4,10)-connected net constructed by tetranuclear [NaCd3(μ3-OH)(COO)5]+ units. Compound 3 exhibits a 3D (3,4,8)-connected net based on binuclear [Cd2(COO)2] units. Compound 4 is a 3D binodal (3,9)-connected framework constructed by trinuclear [Cd3(COO)4] unit...
