NIR luminescence of gadolinium porphyrin complexes
Most lanthanide porphyrin derivatives exhibit ‘normal’ absorption spectra with Q and B bands. The rare earth ions have little effect on the absorption spectra, which are much like those of other closed-shell metalloporphyrins. However, their emission spectra vary according to which lanthanide ion is present. We observe two types of emissions: (i) a line emission arising from the lanthanide ion ...
متن کاملCooperation between metal and ligand in oxygen atom transport by N-confused porphyrin oxorhenium(V) complexes.
N-Confused porphyrin oxorhenium(V) complexes were prepared and their X-ray structures were elucidated. The oxorhenium(V) complexes can transfer oxygen atom from pyridine N-oxide to triphenylphosphine, in which unique cooperation between metal and ligand was observed.
متن کاملHost-guest interactions in acid-porphyrin complexes.
In this report we use the weak interactions of acid-porphyrin complexes to selectively bind competing acids to the faces of a rigid cyclic porphyrin dimer, and characterise the resulting interactions by NMR spectroscopy and nano-electrospray ionisation spectrometry.
متن کاملDimeric iron n-confused porphyrin complexes.
A dimeric iron N-confused porphyrin, [Fe(NCTPP)]2 was obtained from the anaerobic reaction of Fe(NCTPP)Br with NaSePh while under aerobic conditions a hydroxo bridged iron dimer with Na bridging the outer-N atoms was obtained and oxygenation occurred on the inner core pyrrolic carbon to form a novel ONCTPP porphyrinic ring.
متن کاملPreparation of Symmetrical Tetraphenyl Porphyrin Metal Complexes and Their Spectroscopic Studies
Porphyrins molecules are gaining importance in the present era. Porphyrins are important part of biological molecules like hemoglobin and chlorophyll .Photo system 1 and photo system 2 is important sunlight trap in chloroplast. Electron transport chain is a series of chemical reaction in which energy is formed in the form of ATP (Adenosine triphosphate).The members of electron transport chains ...
