With the formation of novel organometallic macromolecules in mind, the polycondensation of transition metal ions and bridged cyclopentadienyl ligands was studied. To this end solvated salts MX2 (M = Fe, Ni, and Cr) were treated with a ligand that consisted of two doubly silyl-bridged cyclopentadieny

The design of ligands with units that play the role of both antenna and shield leads to highly luminescent complexes (see scheme) for all lanthanides that emit in the visible region.

Upon irradiation of a C,-symmetric rut-isomer of an ansu-zirconocene dichloride, an interconversion into the Cs-symmetric meso-form is observed until a photostationary state between the two diastereomers is reached. The final rac/meso-proportion and the interconversion rate depend on the structure o
