We report a new transient spectral method utilizing triplet excited state as sensitive reporters to monitor and differentiate the multiplex G-quadruplex/ligand interactions in a single assay, which is a difficult task and usually requires a combination of several techniques. From a systematic study on the interactions of porphyrin (TMPyP4) with each telomeric G-quadruplex: AG3(T2AG3)3, G2T2G2TG...
The mol-ecule of the title compound, C(30)H(42), occupies a special position on an inversion center. The four butyl side chains have all-trans planar conformations, and the alkyl planes are nearly orthogonal to the anthracene plane [C-C-C-C torsion angles of 79.6 (2) and 78.2 (2)°]. The overall mol-ecule has a stair-like shape with the n-butyl groups at the 1 and 8 positions extending towards t...
Synthesis and Characterization of Metal (II) Phthalocyanine Containing N, N-Dimethyl Phenyl Moieties
Synthesized of novel metal (II)- tetra-4-(N,N-dimethyl phenyl) methan-imine phthalocyanines (MTDMPhImPc) [ M = Co, Ni, Cu, Zn] by an effective and suitable method. The tetra-nitrophthalocyanines converted into aminophthalocyanines reduction. Than amino derivatives bearing to form tetra substituted 4-(N,N-dimethyl methane-imine complexes. These compounds were characterized FTIR, elemental analys...
The crystal structure of the title salt hydrate, C(12)H(28)N(+)·Cl(-)·H(2)O, consists of non-inter-acting cations and anions. The water mol-ecule forms hydrogen bonds to two chloride ions, about a center of inversion, generating a planar eight-membered {⋯H-O-H⋯Cl}(2) ring.
the epoxidation of olefins with tetra n-butylammonium periodate, n-bu4/nio4, is catalyzed by six different tetrakis (4-substituted phenyl) porphyrinatomanganese(iii) acetate, mn(t4-xpp)oac, complexes in the presence of imidazole as an axial ligand with low to high yields and complete selectivity at room temperature. while the electronic effects of the highly electron-withdrawing no2 substituent...
