Electronic Coupling in Low Dimensional Hetero-Metallic Halide Hybrids

Low dimensional metal halide hybrids (2D, 1D, 0D) incorporating hetero-metal halide units is of fundamental importance to understanding electronic coupling between distinct excitons of the constituent metal halide units. However, synthesis of such multicomponent one phase systems is challenging. In this talk, I will highlight our current efforts on exploiting various synthetic strategies towards phase pure multi-metallic halide hybrids. I will present the photo-physical properties of such multi-metallic halide hybrids that manifest emissive properties arising due to electronic cross-talk/coupling between the multiple metal halide centers. I will discuss the relevant mechanism/pathway of the observed electronic coupling highlighting energy transfer interaction that are mediated through the structural components of the low dimensional metal halide hybrids. I will conclude my talk by emphasizing the need of robust theoretical calculations and ultra-fast spectroscopy to provide insight to the observed electronic coupling effects in low D hybrids.
