The reaction of diethyl 2-hydroxyazulene-1,3-dicarboxylate
(<b>DEHA</b>) with zinc species (Zn(OAc)<sub>2</sub> and ZnCl<sub>2</sub>) in the presence of various alkali metal carbonates (M<sub>2</sub>CO<sub>3</sub>) was investigated. The resulting complexes
were characterized by nuclear magnetic resonance spectroscopy, Fourier-transform
infrared spectroscopy, elemental analysis, mass spectrometry, single-crystal
X-ray structural analysis, and UV–vis and fluorescence spectroscopy.
The reaction between <b>DEHA</b> and Zn(OAc)<sub>2</sub> in
the presence of Rb<sub>2</sub>CO<sub>3</sub> or K<sub>2</sub>CO<sub>3</sub> as bases afforded <b>Zn-DEHA-Rb</b> or <b>Zn-DEHA-K</b>, respectively, where three <b>DEHA</b> anions were coordinated
to Zn<sup>2+</sup>, with an alkali metal ion as the counter cation.
On the other hand, the reaction between <b>DEHA</b> and Zn(OAc)<sub>2</sub> in the presence of Na<sub>2</sub>CO<sub>3</sub> afforded <b>Zn-DEHA-Na-1</b>, in which four <b>DEHA</b> anions were
coordinated to two Zn<sup>2+</sup> and Na<sup>+</sup>, with two acetoxy
ions present. The reaction between <b>DEHA</b> and ZnCl<sub>2</sub> in the presence of Na<sub>2</sub>CO<sub>3</sub> provided <b>Zn-DEHA-Na-2</b>, where three <b>DEHA</b> anions were coordinated
to Zn<sup>2+</sup>, with Na<sup>+</sup> as the countercation. The
zinc complexes exhibited S<sub>1</sub> emission despite differences
in their structures. Furthermore, the synthesized complexes were mixed
with poly(methyl methacrylate) to form composite films.
