Controlling orthogonal self-assembly through cis–trans isomerization of a non-covalent palladium complex dimer

Self-assembly of a chiral complex dimer held by 16 hydrogen bonds was controlled through configurational isomerization of the metal center.

Light-controlled spin-state-switching rearrangements of transition metal complexes with photochromic ligands

New families of the transition metal complexes with photochromic ligands manifesting photoswitchable magnetic properties determined by the light-induced spin-crossover and configurational isomerization rearrangements are theoretically designed by means of DFT calculations of electromeric forms of the complexes.

A mechanistic study of AIE processes of TPE luminogens: intramolecular rotation vs. configurational isomerization

Though E–Z isomerization is involved, mechanistically it is intramolecular rotation that quenches luminescence of TPE-based AIEgens.

Thermal solid-state Z/E isomerization of 2-alkylidene-4-oxothiazolidines: Effects of non-covalent interactions

Configurational isomerization of stereo-defined 5-substituted and unsubstituted 2-alkylidene-4-oxothiazolidines 1 in the solid state, giving the Z/E mixtures in various ratios, was investigated by 1H-NMR spectroscopy, X-ray powder crystallography and differential scanning calorimetry (DSC). The Z/E composition can be rationalized in terms of non-covalent interactions, involving intermolecular and intramolecular hydrogen bonding and directional non-bonded 1,5-type S...O interactions. X-Ray powder crystallography, using selected crystalline (Z)-4- oxothiazolidine substrates, revealed transformation to the amorphous state during the irreversible Z ? E process. A correlation between previous results on the Z/E isomerization in solution and now in the solid state was established.
