Ferroin is the chemical compound with the formula [Fe(o-phen) 3]SO 4, where o-phen is an abbreviation for 1,10-phenanthroline, a bidentate ligand. The term "ferroin" is used loosely and includes salts of other anions such as chloride. [1] Ferroin is one of many transition metal complexes of 1,10-phenanthroline.
1,10-Phenanthroline is an inhibitor of metallopeptidases, with one of the first observed instances reported in carboxypeptidase A. [11] Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme . 1,10-Phenanthroline targets mainly zinc metallopeptidases, with a much ...
1,10-Phenanthroline (phen) is a heterocyclic organic compound. It is a white solid that is soluble in organic solvents. The 1,10 refer to the location of the nitrogen atoms that replace CH's in the hydrocarbon called phenanthrene. Abbreviated "phen", it is used as a ligand in coordination chemistry, forming strong complexes with most metal ions.
Ligand-Field scheme summarizing σ-bonding in the octahedral complex [Ti(H 2 O) 6] 3+. In molecular symmetry terms, the six lone-pair orbitals from the ligands (one from each ligand) form six symmetry-adapted linear combinations (SALCs) of orbitals, also sometimes called ligand group orbitals (LGOs).
phen = 1,10-phenanthroline; (μ 2-Oxalato-O,O',O'',O''')-diaqua-bis(1,10-phenanthroline)-di-copper(ii) dinitrate [Cu 2 (ox)(phen) 2 (H 2 O) 2](NO 3) 2: monoclinic P2 1 /n: a=7.128 b=11.715 c=16.529 β=91.80° [20] 4,4’-bipyridine; 1,10-phenanthroline; [Cu 2 (ox)(4,4’-bpy)(phen) 2](NO 3) 2: 855.72 monoclinic C2/c: a=23.144 b=10.6601 c=13. ...
Platinum forms the square planar complexes [PtX 2 (2,9-dimethyl-1,10-phenanthroline)]. [7] Neocuproine has also been discovered to have properties that cause fragmentation and disappearance of the melanin in adult zebrafish melanocytes. Those expressing eGFP also have been observed to lose eGFP fluorescence in the presence of neocuproine. [8]
The optical spectrum of this d 6 octahedral complex exhibits an intense absorption near 250 nm corresponding to a transition from ligand σ MO to the empty e g MO. In IrBr 6 2−, which is a d 5 complex, two absorptions, one near 600 nm and another near 270 nm, are observed. These are assigned as two LMCT bands, one to t 2g and another to e g.
These techniques can be combined with microscopy, to map the intensity (confocal microscopy) or the lifetime (fluorescence-lifetime imaging microscopy) of the photoluminescence across a sample (e.g. a semiconducting wafer, or a biological sample that has been marked with fluorescent molecules). Modulated photoluminescence is a specific method ...
