“…PMO-A specific surface area = 157 m 2 /g; PMO-B specific surface area = 144 m 2 /g. on previously published work (Awawdeh et al, 2003;Kibbey and Meyerhoff, 1993;White and Harmon, 2004). Reflectance and fluorescence experiments indicate a lower concentration of porphyrin per square meter in the imprinted PMO (PMO-B) as compared to the non-imprinted PMO (PMO-A).…”

“…The bands comprising the emission spectrum are more distinctly separated and the ratio of their intensities is different from that of the porphyrin in solution. The change in porphyrin spectrophotometric characteristics upon immobilization has been well documented (Awawdeh et al, 2003;Kibbey and Meyerhoff, 1993;White and Harmon, 2004). The difference spectra presented in Fig.…”

“…Amino acids are the building blocks of proteins that are considered to be very important for most of the processes in living organisms [10]. The presence of acidic carboxyl and basic amino group paves the way for the formation of zwitter ion or dipolar ion as a result of internal neutralization reaction.…”

Novel semi-organic single crystals of bis (Lproline) cadmium iodide (BLPC) were grown by slow evaporation technique. The crystal structure was determined by single-crystal X-ray diffraction studies. Singlecrystal X-ray diffraction study shows that [BLPC] crystallizes in orthorhombic system with space group P2 1 2 1 2 1 . 1 H NMR and 13 C NMR studies were conducted for the grown crystal. Functional groups present in the compound were identified by FTIR spectral studies. The UV-Vis-NIR spectrum was studied to analyse the optical properties of the grown crystals. Thermogravimetric analysis was carried out to study thermal behaviour of the materials. Vickers microhardness measurement was carried out for different loads. Etching studies were carried out using water as etchant. The second harmonic generation efficiency was determined by the Kurtz powder method and it was found to be higher than that of potassium dihydrogen phosphate.

“…[1][2][3][4][5][6][7][8][9][10] In the metallation of porphyrins, depending on size, charge, and spin multiplicity of metal ions, they can fit into the center of the porphyrin ring, forming regular metalloporphyrins, or several of them are located out of the ligand plane, resulting in sitting-atop (SAT) complexes. 11 For the first time, these complexes were indicated as intermediate in the metallation processes of the protoporphyrin dimethyl ester in chloroform, in which two pyrrolenine nitrogens coordinate to the metal ion and two protons on the pyrrole nitrogens remain.…”

A series of sitting-atop (SAT) complexes, [(ZrO)H2t(X)pp(NO3)2], have been prepared via the reactions of free base meso-tetraarylporphyrins, H2t(X)pp, with zirconyl nitrate hydrate, ZrO(NO3)2·xH2O. The products have been characterized by a variety of methods including 1 H NMR, 13 C NMR, IR and UV-Vis spectroscopies, elemental analysis and conductance measurements. The data indicate that the meso-tetraarylporphyrins coordinate with two pyrrolenine nitrogen atoms to the zirconyl cation located above the distorted porphyrin plane and two protons remain on the pyrrole nitrogens. Such half sandwich-type sitting-atop complexes may be considered as models for the initial steps of the metallation of the macrocycles.
