Abstract:
There has been significant interest in incorporating chromophoric compounds into optoelectronic applications based on metal-organic frameworks (MOFs). This approach has provided materials that can be easily integrated into devices, including photovoltaics, light-emitting diodes, and transistor-related applications.[1]
Phthalocyanines are a family of synthetic analogues of porphyrin compounds chemically and thermally stable, which makes them useful in applications that require robust materials. They are excellent electron donors, making them useful in optoelectronic devices.[2] Additionally, phthalocyanines can be easily modified by attaching different chemical groups to their periphery or to the axial position, which allows for fine-tuning of their properties. In this context, silicon phthalocyanines (SiPc), equipped with axial coupling groups, represent a good candidate to combine with metallic atoms, to afford MOF-based chromophoric assemblies, where the inter-linker and metal ion distances, as well as the overall geometry, are crucial parameters to tune the electronic coupling between MOF building blocks. Recently, we have shown that MOF thin films can be successfully assembled using SiPc as linkers, resulting in a porous material that can be used as an optical resonator.[3]
In this communication, we will present our recent advances on SiPc compounds, axially functionalized with carboxylic acid appends and peripherally substituted with different groups and the evaluation of their capability to generate, in combination with Zn atoms, optically active SiPc-based MOF thin films which show systematically tuned J-type electronic coupling.[4]
