Abstract:

The azobenzene containing metal complexes with different length carbon chains have ben synthesized. The compounds have been characterized by spectrophotometric methods as well as thermal, and X-ray diffractometric analysis. It is found that the carbon chain length between azobenzene moiety and diamine metal complex have a great influence on the thermal and fluorescent behavior of the bifunctional compounds. The advantage of combining azobenzene chromophore with metal complex is evidenced by the remarkable high efficiency of azobenzene isomerization behavior and two fluorescent emission bands centered at 290 and 560 nm respectively, induced by metal complex part of the compounds. The holographic image inscription and readout experiment by one of the metal complexes in PMMA matrices is successful.
