Since the first example of tris(8-hydroxyquinolinato)aluminum (Alq3) by Tang and Van Slyke in 1987 as a green emitter, continuous efforts have been made to search for useful organometallic luminophores based on quinolinate derivatives to widen their applicability in various optoelectronic fields. To date, studies on systematic substitution at the C2- or C5-position in the quinolinate ligand to manipulate the HOMO–LUMO energy levels have mainly been investigated. Although such a strategy has been extensively examined, a detailed investigation of the optical properties induced in the variation of the number of quinolinate units has not been reported. We thought that the sequential introduction of multi-quinolinate units into the metal center could give rise to synergistic effects on photophysical properties and provide significant insight into the relationship between the number of ligands and the luminescent properties of the corresponding quinolinol-based organometallic luminophores. Herein, we investigated a series of indium quinolinates using a combination of experimental and theoretical techniques. In this oral presentation, the detailed synthetic aspects and photophysical properties of all the compounds (Inq1, Inq3, and InMeq1‒InMeq3) will be presented.
