Abstract
Trivalent iridium complexes have been recently studied due to the extent of its overlap with the solar spectrum as well as the accessibility of its ligand-ligand charge transfer (LLCT) transition in the UV region. Entrapment of the complex inside faujasitic zeolite NaY converts the dye molecule into a heterogeneous catalyst that has greater stability and usability than the free complex. Ship-in-a-bottle assemblies of trisphenanthroline iridium (III) complex unto zeolite NaY were found to produce singlet oxygen upon illumination. The possible use of these solid-state catalyst for waste water treatment was examined by using 9,10-dimethylanthracene (DMA) as a chemical trap for singlet oxygen. The degradation spectra was observed to be pseudo-first order with respect to DMA. Varying the time of illumination showed that the amount of DMA degraded was directly dependent on the length of UV irradiation.
