The novel two homologous phthalocyanine (Pc) series (azo- and oxo-bridged) substituted with a 5-bromo-2-methoxyphenyl moiety were synthesized and characterized. The physical and chemical properties of the Pcs were compared with each other for the first time. The ac response of the Pcs was also studied by impedance measurements over a temperature range of 300-500 K. The real and imaginary parts ...

A graph (I’ is bridged if it contains no isometric cycles of length greater than 3. For each positive integer p, let Tp be the graph obtained by triangulating an equilateral triangIe of side p with equilateral triangles of side 1. It is shown that the radius and diameter of a bridged graph containing no isometric TP satisfy the inequality 6r s 3d +p + 3. Thus, for each 8xed p, the radius of a b...

Results: Approximately 80% of patients had AWR with component separation and 8% had a bridged repair. The most frequently used mesh was porcine (Strattice, 56.5%), followed by bovine (Surgimend, 31.1%) and human (Alloderm, 10.9%). There were 31 (16.2%) hernia recurrences with a surgical site occurrence rate of 25.1%. Among these patients, 13% had hernia recurrence within 3 years, while 16.7% at...

Two new dicyanamide bridged complexes [Mn(μ1,5-dca)2(salicyh)2]n (1) and {[Ni(μ1,5-dca)(TTA)](ClO4)}n (2) (dca = dicyanamide, ; salicyh = salicylic hydrazide; TTA = triethylenetetramine) have been synthesised and structurally characterised. Both the compounds 1 and 2 consist in 1-D coordination polymers. In 1 the manganese atoms are doubly bridged by μ1,5-dca ligands, whereas in 2 the nickel at...

The selective response of supramolecular structures, cavitands, is demonstrated using a sensitive optical transduction scheme, surface plasmon resonance (SPR). The methylene bridged cavitands (MeCav) with shallow cavities do not complex aromatic vapors, the pyrazine bridged cavitands (PzCav) show intermediate selectivity whereas the quinoxaline bridged cavitands (QxCav) with the deepest cavitie...

Thirteen bridged triazolium and imidazolium dicationic salts, which uniquely pair closo-icosahedral perfluoroborane [B(12)F(12)](2-), borane [B(12)H(12)](2-), or carborane [CB(11)H(12)](-) anionic species with unsaturated bridged heterocyclium dications, were synthesized using an aqueous benchtop method. This considerably extends the scope of a reported aqueous synthesis of binary [heterocycliu...

Novel nitrogen-bridged diazocines (triazocines) were synthesized that carry a formyl or an acetyl group at the CH 2 NR-bridge and bromo- iodo-substituents distant phenyl ring. The photophysical properties investigated in acetonitrile water. As compared to previous approaches yields of intramolecular azo cyclizations increased (from ≈40 60%) using oxidative approach starting from corresponding a...

2-Borylated porphyrins reacted with Pt(cod)Cl2 to give b-to-b platinum-bridged porphyrin dimers, which were converted to b-to-b directly linked porphyrin dimers through triphenylphosphine-mediated reductive elimination. Similar reactions of 2,18-diborylated Ni(II)–porphyrin and Zn(II)–porphyrin gave the corresponding doubly b-to-b platinum-bridged porphyrin dimers. Treatment of the doubly b-to-...
