- Fluorescence sensing based on cation-induced conformational switching: Copper-selective modulation of the photoinduced intramolecular charge transfer of a donor-acceptor biphenyl fluorophore
-
The fluorescence emission energy of donor-acceptor substituted biphenyls is highly sensitive towards conformational changes of the interannular twist angle. By integrating 4-dimethylamino-4′-cyano-biphenyl into the ligand backbone of a thioether-rich metal receptor we designed a fluorescence sensor that exhibits high selectivity towards copper. Upon metal binding the ligand undergoes a significant conformational change, which induces a strong hypsochromic shift of the photoinduced charge-transfer emission. Steady-state absorption and fluorescence spectroscopy revealed a high affinity towards Cu(I) with a well-defined 1:1 metal-ligand complex stoichiometry. The nature of the conformational changes upon Cu(I) coordination were analyzed in detail by 1H NMR and 2D NOESY experiments. The spectroscopic data provide a coherent picture, which is consistent with a Boltzmann ground-state distribution of several rotamers that are locked into a more flattened geometry upon coordination of Cu(I).

- Photocyclization of Aryl Halides. Part 4. 5-(2-Halogenophenyl)-1,3-diphenyl-Δ2-pyrazolines. Predissociation and Electron Transfer between Intramolecular but Separate Chromophores
-
Photoreaction of 5-(2-iodophenyl)-1,3-diphenyl-Δ2-pyrazoline proceeds by simple bond homolysis from the S1deg state to give 1,3,5-triphenylpyrazoline and 2-phenylpyrazolophenanthridine in a ratio which depends on the hydrogen atom donor ability of the hydrocarbon solvent.The quantum yield for decomposition of the iodo-compound depends on the viscosity of the hydrocarbon solvent and on the temperature.The corresponding chloro- and bromo-compounds as well as the 3-iodo- and 4-iodo-phenyl compounds are photostable.Consideration of these facts and the complementary fluorescence data suggest a mechanism of interchromophoric predissociation to an n?* state.However, examples are given where there is a smaller electron donor-acceptor energy gap between the two chromophores so that photoreaction occurs by an electron transfer pathway.
