An efficient synthesis of high generation conjugated polyphenylene dendrimer‐based β ‐diketones was investigated using simple synthetic methods. The new dendrimer‐based β ‐diketones were characterized by NMR, MS and elemental analysis. The UV‐Vis and fluorescence spectra of these β ‐diketones in different solvents were investigated. The photoluminescent (PL) quantum yield and TG and DSC curves were also investigated. A new intermediate, 1‐bromo‐3,5‐diiodobenzene, was developed to synthesize high generation dendrimers with good yields.
