Аннотация доклада:
We studied 15-crown-5 ether mono- and bis(styryl) derivative of 2,2'-bipyridine as a scaffold to construct photoresponsive complexes with Cd2+, Zn2+, Hg2+, Co2+, Fe2+, H+, Ba2+, Ca2+ in MeCN. Absorption and emission spectroscopy, 1-D and 2-D 1H-NMR spectroscopy and ESI-mass spectrometry were used in our investigation. Optical properties of one dimensional (1D) Ca2+– containing and octahedral 3D Zn2+– containing complexes with crowned styryl derivatives of 2,2'-bipyridine were described. Bimetallic Ca2+, Zn2+ – containing complexes possess well-defined structures and particular optical characteristics. Properties of the zinc polypyridyl complexes are modified by intermolecular interactions between the crown ether center and the metal ions, so they are potentially useful in the preparation of chemical sensors
