Abstract

A flexible ligand bis(7-methyl-1,8-naphthyridine-2-ylamino)methane (L), having κ⁴-chelating and κ²-bridging modes, and its intriguing structural complexes of Zn(II) with μ-OH, κ¹-OAc, μ-κ¹-OAc and μ- κ²-OAc ligands, [Zn₂(L)₂(OH)](ClO ₄)₃ (1), [Zn₄(L)₂(OAc) ₆(OH)₂]·CH₂Cl₂ (2·CH₂Cl₂) and [Zn₅(L) ₂(OAc)₁₀]_n·4nH₂O (3·4H₂O) were synthesized and their structures were determined by X-ray crystallography. These compounds exhibited intense blue fluorescent emissions with a λ_max in the range of 380-410 nm in CH ₂Cl₂, CH₃CN and CH₃OH solutions, and solid-state emissions centered at 416, 463, 490 and 451 nm were observed for the compounds L, 1, 2 and 3 at room temperature, respectively. The investigated fluorescence properties of L associated with various metal ions showed that the fluorescence enhancement of L with Cd(II) was more sensitive than with other interfering cations.
