The new biomimetic ligands N4Py2Ph (1) and N4Py 2Ph,amide (2) were synthesized and yield the iron(II) complexes [FeII(N4Py2Ph)(NCCH3)](BF4) 2 (3) and [FeII(N4Py2Ph,amide)](BF 4)2 (5). Controlled orientation of the Ph substituents in 3 leads to facile triplet spin reactivity for a putative FeIV(O) intermediate, resulting in rapid arene hydroxylation. Addition of a peripheral amide substituent within hydrogen-bond distance of the iron first coordination sphere leads to stabilization of a high-spin FeIIIOOR species which decays without arene hydroxylation. These results provide new insights regarding the impact of secondary coordination sphere effects at nonheme iron centers.

Page/Page column 32, (2008/06/13)
Provision of a novel platinum complex which is useful as a material for a light-emitting device of good light emission characteristic and light emission efficiency, and a novel light-emitting material that may be utilized in various fields. A platinum complex represented by the following general formula (1): (in which two rings of ring A, ring B, ring C, and ring D represent nitrogen-containing heterocyclic rings which may have a substituent and the remaining two rings of them represent aryl rings or hetero aryl rings which may have a substituent, the ring A and the ring B, the ring A and the ring C or/and the ring B and the rind D may form condensed rings. Two of X1, X2, X3, and X4 represent nitrogen atoms coordination bonded to a platinum atom and the remaining two of them represent carbon atoms or nitrogen atoms. Q1, Q2, and Q3 each represents a bond, oxygen atom, sulfur atom or bivalent group, two of Z1, Z2, Z3, and Z4 represent coordination bonds, and the remaining two of them represent covalent bonds, oxygen atoms or sulfur atoms), and a light-emitting device containing the platinum complex.
