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.
