Synthesis, spectroscopy, photophysics of multi-chromophoric Zn(II) group 8 metal complexes

摘要

Novel multichromophoric complexes comprising the formula R1-RA-[MC]-([RM]z-[MC])m-RA-R2 are provided. Polymeric compositions and devices comprising the same are also discussed. The complexes are characterized by a central bridging moiety comprising one or a plurality of linked conjugated macrocyclic molecules [MC] coupled to at least one inorganic moiety (R1 and/or R2) through organic linker RA. Preparation methods include metal-mediated cross-coupling techniques. The complexes can be useful in nonlinear optical devices and other optoelectronic applications.
