The fictitious spin-1/2 Hamiltonian approach is the putative method to analyze the fine-structure/hyperfine ESR spectra of high spin metallocomplexes having sizable zerofield splitting (ZFS), thus giving salient principal g-values far from around g =

A series of novel 1,9-diazodipyrrins (4) were readily synthesized by reacting aryldiazonium salts with 5-aryldipyrromethanes under both acidic and basic conditions. The zinc complex of 1,9-diphenylazodipyrrin (5aZn) was confirmed by X-ray crystallogr

The reaction of an α-free, β,β'-linked bis(dipyrromethene) ligand with Fe(3+) or Co(3+) led to noninterconvertible triple-stranded helicates and mesocates. In the present context, a stable α-free ligand 2 has been developed and complexation of li

Starting from commercially available 3-methylindole and 1,3-diiminoisoindoline, the BF2 complex of indol-2-yl-isoindol-1-ylidene-amine (7) has been prepared in three steps; its wavelength of maximum visible absorption is similar to that of a tetra-ph

A meso-2,6-dichlorophenyl pentapyrrin was prepared using a modified method for dipyrrane synthesis followed by simple DDQ oxidation. The fully conjugated structures formed via redox inter-conversions were studied using crystallographic as well as obs

We report the direct observation of 1D and 2D nanostructures of cobalt dipyrromethene trimer complexes adsorbed on a highly oriented pyrolytic graphite surface using scanning tunneling microscopy (STM). STM images showed two types of ordered structur

The therapeutic agents flunarizine and lomerizine exhibit inhibitory activities against a variety of ion channels and neurotransmitter receptors. We have optimized their scaffolds to obtain more selective N-type calcium channel blockers. During this

Symmetric 2,5-bisazopyrroles 2(a-d) were synthesized by a one-step reaction of substituted phenyl diazonium salts [R'(Ph)N2(+)Cl-] [a, R' = 4-N(CH3)2; b, R' = 2-OH; c, R' = 2-CO2H; d, R' = 4-NO2] with pyrrole under basic conditions. Asymmetric 2,5-bi
