4-hydroxyphenyl 1,10-phenanthroline

Synthesis of TTF-phenanthroline macrocycles (e.g., 13) were accomplished in a simple multi-step sequence the macrocyclization procedure was from the 2,9-di(p-hydroxyphenyl)-1,10-phenanthroline with TTF-diiodide under high dilution conditions in the presence of CS2CO3 <00CC215>. 

There are both geometric and kinetic differences between the interactions of A- and A-[Ru(bpy)2(hpimp)]2+ hpimp=2-(2-hydroxyphenyl)imi-dazo [4,5-/]-1,10-phenanthroline and the hexanucleotide d(GTCGAC)2. The A-isomer penetrates more deeply into the major groove of the polynucleotide it also binds more rapidly than the A-isomer to DNA (156). 

Several directed syntheses of catenanes have also been reported. One of these relies upon coordination of ligands to a metallic ion to achieve the proper geometry. An example is shown in Figure 19.1,729 2,9-Bis(/7-hydroxyphenyl)-l, 10-phenanthroline 40 is converted to the macrocycle 42 by treatment with the polyether 41, in a Williamson reaction, under... 

Mixing of equimolar solutions of [Cu(CH3CN)4]PF6 in acetonitrile and Zn porphyrin-containing macrocycle 44 [80] in dichloromethane, followed by addition of phenanthroline derivative 45 in dichloromethane afforded in quantitative yield precatenate 48" . Subsequently, this complex was combined with a stoichiometric amount of gold(III) 5,10-di(p-hydroxyphenyl)-15,20-di(3,5-di-fert-butylphenyl)porphyrinate [47] PF6 in DMF. The resulting so-... 

Out of more than forty different porphyrinic and non-porphyrinic organic and inorganic electrocatalysts tested for these properties, only three show the desired characteristics tetrakis (3-methoxy-4-hydroxyphenyl)porphyrin, me50-tri(V-methyl-4-pyridinium)-p-phenylene-5 -0-2, 3 -0-isopropylideneuridine (PUP), and NA -bis[5-p-phenylene-10,15,20-tris(3-methoxy-4-hydroxyphenyl)-porphyrin]-l,10-phenanthroline-4,7-diamide( 1,10-phen)(TMHPP)2." Detection limit for NO depends on film quality and varies between 10 and 10 M. The best sensitivity is usually obtained using a PUP and (l,10-phen)(TMHPP)2 films with Ni(II) as the central metal. If a reproducibility of preparation procedure is considered (l,10-phen)(TMHPP)2 Ni(II) is much superior (failure rate 1 10) in comparison to two other porphyrins.

Besides the o-hydroxyphenyl amide (salicylamide) ligand used by the above workers, a plethora of other ligands such as phosphanes and diols (BINOL) have been used [77], and diketones, amino acids, 1,10-phenanthroline (phen) derivatives, oxalyldihydrazone, and phosphoramidite ligands have also been used [76].
