In the present work, 2-ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline (EEDQ) was used as an effective coupling agent to design and synthesize a diversity of post-functionalized polyoxomolybdate (POM) hybrids based on an Anderson-type POM cluster and incorporating various organic molecules. Subsequently, the synthesized hybrids were characterized via various analytical and spectroscopic techniques including FT-IR spectroscopy, ESI-MS, H-1 NMR spectroscopy, and elemental analysis. The present investigations revealed that different factors such as alkyl chain length, steric effect and electrophilicity had a profound effect on the post-functionalization of the Anderson-type POM cluster utilizing EEDQ as the coupling agent. By extensively investigating the effect of EEDQ on the efficient post-functionalization of an Anderson-type POM cluster, EEDQ can be more effectively utilized for post-functionalizing the POM clusters towards the future construction of various organic-inorganic hybrids.
