Novel porphyrin Schiff bases were synthesized by a simple Schiff base condensation in refluxing toluene between 5-(4-aminophenyl)-10,15,20-triphe?nylporphyrin (ATTP) 3 and styryl aldehydes 4-6 or p-halobenzaldehydes 7-9. The newly synthesized porphyrin Schiff bases were characterized on the basis of their chemical properties and spectral data. A good intramolecular energy transfer from the styryl unit to the porphyrin moiety was found.

Tetraazamacrocyclic Ligands

A series of oxovanadium(IV) complexes of the type [VO(mac)]SO4(where mac = tetraazamacrocyclic ligands derived from condensation of 4,4,4-trifluro-1-(2-furyl)-1,3-butanedione or 4,4,4-trifluro-1-(2-thenyl)-1,3-butanedione withp-phenylenediamine and their reaction withβ-diketones) have been prepared using oxometal ion of vanadium as kinetic template. These complexes have been ascertained by electrical conductance, magnetic moment, elemental analyses, infrared, e.s.r. and electronic spectral data. All the oxovanadium(IV) complexes are five-coordinate ones.

By reactions of indium chloride tetrahydrate with three bis-Schiff bases ligands (N, N’-bis (3-methoxy-salicylidene)benzidine = L1; N, N’-bis (3-methoxysalicylidene)-2, 2’-dimethyl- benzidine =L2; N, N’-bis (3-methoxysalicylidene)-o- dianisidine = L3), respectively, three novel corresponding complexes 1~3 were obtained. The complexes were characterized by infrared spectrum, molar conductance, elemental analysis and thermal gravimetric analysis. The chemical formulae of the complexes 1~3 were determined as (InCl3)2Ln (1, n = 1; 2, n = 2; 3, n = 3). All the complexes are constructed with binuclear indium ions. Every complex consists of two central In (III) ions, one corresponding bis-Schiff base ligand and six Cl-.

The cyclic (2+2) template condensation of pyridine-2,6-dicarboxaldehyde with 1,2-Bis(2- aminoethoxy) ethane using Pb(SCN)2 gave dinuclear lead (II) complex, Pb2L1(SCN)4 where L1 is a tetra-Schiff-base macrocycle. The transmetallation treatment of Pb2L1(SCN)4 with Cu(ClO4)2.6H2O yield the complex, [Cu2L1(SCN)3(ClO4)] which has been characterized by elemental analysis, IR, ESI-MS spectroscopy and X-ray crystallography. On the basis of spectral data, different geometry of Cu2+ has been suggested. DOI: http://dx.doi.org/10.3329/jbas.v36i1.10924 Journal of Bangladesh Academy of Sciences, Vol. 36, No. 1, 89-96, 2012
