In this research, dipeptide (his-β-alanine) and porphyrin derivatives were choosen for comparing chelating ability of toxic metals such as Al3+, Cu2+, Hg2+ and Pb2+ in vitro. The reason for choosing these two compounds is that both of them are naturally present in biological systems and comparison of chelating ability of these two compounds has not yet been done. Synthesis and comparison of kin...
Two compounds containing a porphyrin dimer and a perylene tetracarboxylic diimide (PDI) linked by phenyl (1) or ethylene groups (2) are prepared. The photophysical properties of these two compounds are investigated by steady state electronic absorption and fluorescence spectra and lifetime measurements. The ground state absorption spectra reveal intense interactions between the porphyrin units ...
Ammonia (NH3) is regarded as a renewable energy source well an important molecule for agricultural applications. The energy-intensive Haber-Bosch method produces large amounts of CO2 gas during ammonia production. As alternative, there has recently been much interest in the electrocatalytic production NH3 via electrochemical nitrogen reduction reaction (ENRR) process utilizing under ambient con...
