Photoisomerization: N-phenylcarbazole-conjugated dimethyl 2,3-diethynylfumarate/maleate, E/Z-4, shows highly efficient and reversible visible-light E/Z photoisomerization (φtotal=0.40) upon excitation with an intramolecular charge-transfer band. This photochromism induces switching of electronic communication between the two N-phenylcarbazole moieties in the one-electron oxidized mixed-valent state (see scheme). Copyright

A series of tetracationic M2L4 palladium-pyridyl complexes with endohedral amine functionality have been synthesized. The complexes were analyzed by NMR techniques (including Diffusion NMR and 2D NOESY), electrospray ionization (ESI) mass spectrometry, and X-ray crystallography. The solid state analysis shows a large change in crystal morphology upon introduction of the endohedral amine groups, caused by deleterious interactions between the amines and the triflate counterions from the coordination process. Combination of different ligands allows analysis of ligand exchange rates via NMR analysis, with half-lives on the order of 3 h, independent of the donor properties of the ligand. Self-sorting behavior is observed, with more electron-rich ligands being favored. The amine-containing and extended complexes are strongly fluorescent, giving quantum yields of up to 83%.
