由於銥(III)錯合物有強的自旋-軌域耦合作用，導致其磷光效率相較於其他有機金屬錯合物來的好，常被用來作為OLED的有機發光層材料。
一般常見於文獻中合成銥(III)的mer與fac兩種homoleptic異構物的方法皆以有機溶劑作為反應環境，藉由溫度的控制以及管柱層析法的分離分別得到兩種異構物。
本篇嘗試利用水熱法的合成方式，以IrCl3·nH2O為起始物與緩衝溶液進行反應。藉由調控反應的溫度與時間等條件，以一鍋法的方式和簡單的過濾方法，合成出一系列mer-Ir(N^C)3的立體異構物，其中N^C = ppy、4’-CH3ppy、2’,4’-dFppy、5-CH3ppy、5-Fppy、5-CH3-4’Fppy、4’-OCH3ppy、4’-Fppy。在反應過程中可以減少有機溶劑的使用，讓該系列化合物的合成更符合綠色化學的精神。(以上的化合物皆經由核磁共振光譜、電噴灑游離質譜、紫外-可見光吸收光譜以及光致發光光譜進行分析與鑑定)

The meridional iridium(III) complexes, mer-Ir(N^C)3 are prepared from hydrothermal synthesis. IrCl3·nH2O complexe and monoanionic cyclometalating ligand, HC^N (HC^N = Hppy、4’-CH3ppy、2’,4’-dFppy、5-CH3ppy、5-Fppy、5-CH3-4’Fppy、4’-OCH3ppy、4’-Fppy) are heated to 60-200 °C in 10 mL buffer solution for 24-72 hour.
