Resumen
This thesis begins with presenting a thorough review of m-BPDM analogues and their metal complexes. The literature review led us to the foundation of research gap. The studies were then diverted towards finding out the factors that could enhance the stability of the free base analogues of m-BPDM systems. Hence, in the next two chapters (4 and 5) the effect of substitutions at meso and C3-positions, studied computationally, has been presented. Molecular tailoring approach has been incorporated in order to find out the intramolecular hydrogen bond energies. The energies so obtained have been correlated with other factors obtained from the optimized geometry’s results, like the study of non-covalent interactions (NCI), frontier molecular orbital (FMO) visualization, molecular electrostatic surface potential (MESP) etc. We then moved to the synthesis of a new sterically hindered analogue of m-BPDM and its zinc and cadmium chloride complexes, viz. Chapter 6 of this thesis. The synthesis was confirmed by UV-Vis, 1H-NMR and mass spectrometry. The X-ray solid state structures stated the presence of two conformers of m-BPDM viz. syn and anti. It was found that crystal structures constituted varied conformers depending upon the group present at sp 3 meso carbon atoms. Thus, through chapter 7, we intend to understand the effect of substitution at meso-carbon atoms on the metalated (Zn(II) and Cd(II)) m-BPDM conformer stability.

Zinc is an essential metal ion in biology system. Over two hundred enzymes contain zinc in their active site in human body. They play important roles in bio-relate catalytic reactions. In this thesis, we demonstrate a new porphyrin analogue, m-benziporphodimethene (BPDM), as a highly selective fluorescence sensor for zinc ion. When zinc(2+) coordinated with BPDM to form a stable metal complex, the excitation by long wavelength light emits long wavelength fluorescence through chelation-enchanced fluorescence effect. To confirm the penetration of compounds into cells, we treat BPDM-Zn into medium of HeLa cell before incubation and detect the fluorescence by a high performance confocal microscope. In addition, we study the 24 hours cell toxicity of DMSO and BPDM-COOH in HeLa cell measured by MTT assay and ELISA reader. Finally, we also utilized BPDM-COOH as a sensor to trace the apoptotic process in HeLa cell. In the second chapter, we successfully synthesize a heteroatom substituted expanded porphyrin, [38]octaphyrin(1,1,1,1,1,1,1,1), embeding four nitrogen atoms and four sulfur atoms in the central core, which confirmed by one dimension 1H NMR, two dimensions 1H−1H COSY, 1H−13C HSQC, 1H−13C HMBC NMR spectra and single crystal structure. Interestingly, variable temperature 1H NMR experiment demonstrated a temperature dependent molecular structure ring current changes. Additionally, protonation by HClO4 also affects the structure and aromaticity of [38]N4S4-octaphyrin according to UV-vis and 1H−NMR spectroscopic data.
