Thesis tittle: Contracted and Expanded Porphyrin analogues: Syntheses, Conformation, Aromaticity and Coordination ChemistryBrief description of research output: Novel contracted and expanded porphyrin analogues were synthesized by incorporation of (a) higher arene unit such as biphenyl and terphenylene moiety, (b) pyridine units and studied their properties. Also these analogues were explored for (i) NIR absorbing dyes; (ii) cooperative/multi metal complexes; (iii) dual aromatic… Show more Thesis tittle: Contracted and Expanded Porphyrin analogues: Syntheses, Conformation, Aromaticity and Coordination ChemistryBrief description of research output: Novel contracted and expanded porphyrin analogues were synthesized by incorporation of (a) higher arene unit such as biphenyl and terphenylene moiety, (b) pyridine units and studied their properties.

Specialization in Inorganic Chemistry.Internship project tittle: Synthesis and characterization of ternary copper(II) complexes with a tetradentate N4 donor di-Schiff base and halidesBrief description of project: Three new copper(II) complexes, [Cu(L)(Cl)]ClO4, [Cu(L)(Br)]ClO4 and [Cu(L)(I)]ClO4 have been prepared from a tetradentate symmetrical Schiff base, N,N'-bis-(1-pyridin-2-yl-ethylidene)-propane-1,3-diamine (L) and characterized by elemental analysis, IR and UV-Vis… Show more Specialization in Inorganic Chemistry.Internship project tittle: Synthesis and characterization of ternary copper(II) complexes with a tetradentate N4 donor di-Schiff base and halidesBrief description of project: Three new copper(II) complexes, [Cu(L)(Cl)]ClO4, [Cu(L)(Br)]ClO4 and [Cu(L)(I)]ClO4 have been prepared from a tetradentate symmetrical Schiff base, N,N'-bis-(1-pyridin-2-yl-ethylidene)-propane-1,3-diamine (L) and characterized by elemental analysis, IR and UV-Vis spectroscopy and single-crystal X-ray diffraction studies. Extended supra-molecular networks were generated through different weak noncovalent forces. The interplay between the anion-π, π-π interactions and a mutual reinforcement of both interactions were analyzed. Show less
