Syntheses of shuttlecock- and bowl-equipped phenylazopyridines and photomodulation of their coordination ability to Zn-porphyrin

Shuttlecock- and bowl-equipped 4-(phenylazo)pyridine derivatives, which bear substituents that allow the pyridine moiety to protrude in the trans form but hinder it in the cis form, have been designed and synthesized. These molecules show cis/trans photoisomerization despite the presence of bulky substituents. 1H NMR titration with Zn-porphyrin showed that the trans isomers coordinate to Zn-porphyrin much stronger than the cis isomers.

4-Nitrosopyridine 1-Oxide compared with Other 4-Substituted Pyridine 1-Oxides as evidenced by Carbon-13 NMR Spectra and Dipole Moments

Previously unreported physical properties of 4-Nitrosopyridine 1-oxide have been measured; the 13C NMR spectrum is compared with that for other 4-substituted pyridine 1-oxides and it is suggested that the electronic properties of the nitroso group and of other ?-electron-accepting groups are dominated by the N+-O- dipole, this being mirrored by dipole-moment measurements.
