Costero, Ana M. published the artcilePolyazapodands derived from biphenyl. Study of their behavior as conformationally regulated fluorescent sensors, COA of Formula: C8H21N3, the publication is Supramolecular Chemistry (2004), 16(6), 435-446, database is CAplus.

Eight new polyazapodands containing a 4,4′-substituted biphenyl moiety have been synthesized. Four are functionalized on positions 4 and 4′ with a nitro group and four with a dimethylamino substituent. Comparison of the emission behavior of clearly suggests that a modification in the dihedral angle between the biphenyl rings is an important factor in determining the fluorescent response of the mol. The fluorescence is pH dependent, due to the formation of intramol. hydrogen bonds between protonated aliphatic nitrogens and a carbonyl oxygen, which influences the aforementioned dihedral angle. A crystal structure resolved by X-ray diffraction, and confirms the dependence of the angle and the rigidity on the hydrogen bonding. The complexation properties of these ligands have been studied with Zn²⁺, Cd²⁺, Ni²⁺, Cu²⁺ and Pb²⁺, which show that the number of amino groups within the pendants has a strong influence on the nature of the complexation and the fluorescent response of each ligand.

Clark, Andrew J. published the artcileSolid-Supported Copper Catalysts for Atom-Transfer Radical Cyclizations: Assessment of Support Type and Ligand Structure on Catalyst Performance in the Synthesis of Nitrogen Heterocycles, Application of N1,N1,N2-Trimethyl-N2-(2-(methylamino)ethyl)ethane-1,2-diamine, the publication is Journal of Organic Chemistry (2006), 71(4), 1471-1479, database is CAplus and MEDLINE.

A range of solid-supported pyridinemethanimine (PMI) and polyamine ligands were prepared on SiO₂, polystyrene (P), and JandaJel (JJ) supports. The CuCl and CuBr complexes of these supported ligands were used to assess both the effect of the ligand type and the nature of the support upon a representative range of Cu-mediated atom transfer radical cyclizations of 5-exo-trig Cl₃CCON(Ts)CH₂CH:CH₂ (6), BrCMe₂CONTsCH₂CH:CH₂ (24), MeCCl₂CONTsCH₂CH:CH₂ (25), 5-exo-dig Me₂CBrNTsCH₂Cú·CH (26), 4-exo-trig Me₂CBrCONBnC:C(CH₂)₅ (28), and 5-endo-trig derivatives Me₂CBrCON(CH₂Ph)R (R = 1-cyclohexen-1-yl, 27) and MeCHBrCON(CH₂Ph)R (R = 1-cyclohexen-1-yl, 38) to give N-heterocycles. The effect of the nature of the support on the stereochem. outcome of the 5-exo cyclization of 25 was probed. Generally, the type of support (e.g., polystyrene, SiO₂, or JandaJel) had very little effect upon the efficiency and selectivity of the processes, but the nature of the ligand type immobilized was the important factor. Thus, the 5-exo cyclization of 6 and 24–26 proceeded more rapidly with the PMI ligands, whereas 4-exo cyclizations 28 and 5-endo radical polar crossover reactions 27 and 38 proceeded more efficiently with the JJ-TEDETA ligand [Et₂NCH₂CH₂]₂NCH₂CH₂CO₂-JJ (15). The efficiency of the supported ligands was also compared to their solution counterparts. The reusability of P-PMDETA ligand system, Me₂NCH₂CH₂NMeCH₂CH₂NMeCH₂CH₂CH₂-P (13), was assessed in the cyclization of 6.
