Abstract
Multinuclear complexes have attracted great attention because of their superior properties originating from the cooperative effects between the metal ions. In this study, we synthesized polynuclear zinc complexes by chelation between the side-chains of polyhedral oligomeric silsesquioxane (POSS). From the NMR spectroscopy, high-resolution mass spectrometry and Fourier transform infrared spectroscopy (FT-IR), it was confirmed the four equivalents of zinc ions were coordinated to the single POSS molecule. Optical measurements indicated that luminescent properties can be preserved even in the solid state. The three-dimensional structure of POSS should play a significant role in suppressing concentration quenching followed by solid-state emission properties.
