- Abstract
We have designed and synthesized novel luminescent lanthanide complexes based on a naphthalene derivative. The coordination number of complexed ligands with Eu3+ ions is an important parameter to enhance the photoluminescence (PL) intensity. The photoluminescence spectra of Eu(III)-cored complexes exhibit a sharp red emission band at 612 nm, corresponding to the 5D0→7F2 transition of the trivalent Eu ion. The saturated europium complexes (C-2 and C-3) have much stronger PL intensity than the unsaturated 6-coordinated europium complex (C-1), due to the instability of the C-1 complex. In this paper, the synthesis and photophysical properties of novel europium(III)-chelated complexes based on a naphthalene derivative will be discussed.
