Three-chain B(6n+14) cages as possible precursors for the syntheses of boron fullerenes.
Using the first principle methods, we proposed a series of three-chain boron cages B6n+14 (n = 1-12) which are mainly built by fusing three boron semi-double-rings. Their simple geometric structures (approximate D3 or C3 symmetry) facilitate their bottom-up syntheses from the hexagonal B7 and the double-chain boron clusters, such as B2, B4, B6, B8H2, B10H2, B12H2, and the double ring B20. The s...
متن کاملDiamido Complexes of Titanium and Zirconium as Catalyst Precursors for Ethylene Polymerization
A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...
متن کاملSoluble precursors of 2,3-naphthalocyanine and phthalocyanine for use in thin film transistors.
Soluble precursors of 2,3-naphthalocyanine (Nc) and phthalocyanine (Pc) were prepared and were converted into insoluble semiconducting thin films of Pc and Nc by heating after fabrication via spin-coating.
متن کاملImproved syntheses of high hole mobility phthalocyanines: A case of steric assistance in the cyclo-oligomerisation of phthalonitriles
It has been shown that the base-initiated cyclo-oligomerisation of phthalonitriles is favoured by bulky α-substituents making it possible to obtain the metal-free phthalocyanine directly and in high yield. The phthalocyanine with eight α-isoheptyl substituents gives a high time-of-flight hole mobility of 0.14 cm(2)·V(-1)·s(-1) within the temperature range of the columnar hexagonal phase, that i...
متن کاملGlycosylated Metal Phthalocyanines.
In the first part; the syntheses of mono-; di-; and tetra-glycosylated phthalonitriles is described; which are the most used starting materials for the preparation of the corresponding glycosylated metal (mostly zinc) phthalocyanines. In the second section; the preparation of symmetric and unsymmetric mono-; tetra-; and octa- glycosylated zinc phthalocyanines are reviewed; in which the sugar is...
