This work reports the combinatorial synthesis and screening of phosphorescent iridium complexes as solution processable emitters for OLEDs. The approach taken here allows for the rapid synthesis, isolation, spectroscopic characterization and identifi cation of the libraries based on chromatographic methods. Subsequent analysis of the irradiation induced degradation provides insight on the stability of the complexes under continuous excitation. The method is versatile and can easily be applied to other metal complexes or organic dyes for various applications, e.g., in electroluminescence, photovoltaics and sensing.

Syntheses of 1,2‐, 1,3‐, 1,4‐, 1,8‐, 2,4‐, 3,4‐, 4,8‐, 1,2,4‐, 1,2,8‐ and 1,3,4‐functionalized dibenzofurans in few steps with good to excellent yields starting from dibenzofuran‐1‐ol or ‐4‐ol are presented. These rapidly accessible bi‐ or tri‐functionalized building blocks are of great interest for the synthesis of bioactive substances or functional material development. Furthermore, for intermediates containing both a bromine and a triflate moiety, a selective mono‐substitution by means of Suzuki–Miyaura reaction (SMR) is described.
