Abstract:
A chemical technique was developed for batch synthesis of Ir (dfppy)
2 (dtbbpy)
+PF
6-,an organometallic light-emitting molecule for OLED. The process involves cycometalation of chloride-bridged dimer (dfppy)
2 Ir (μ-Cl
2) Ir (dfppy)
2 with 4,4’-ditert-butyl-2,2’-bipyridine by hexafluorophosphate acid to produce the desired compound in a batch scale. The chemical structure of Ir (dfppy)
2 (dtbbpy)
+PF
6-was verified by elemental analysis,NMR(1 H and 13 C),MS and FT-IR along with single crystal X-ray diffraction data. The synthesized Ir (dfppy)
2 (dtbbpy)
+PF
6- is an electrically neutral octahedral complex. The green-emission at room temperature peaked at 500 nm. Single crystals of complex was prepared,via a solvent evaporation technique,and was subjected to X-ray diffraction analysis.The results show complex is in the monoclinic system with a space group of P1
21/c1.
