We successfully introduced up to 12 poly(benzyl ether)dendron-thiols of the second generation (D2SH) into the Au13 core of [Au23(ScC6H11)16]- while retaining the geometric structure. The decoration with D2SH enhanced the optical absorbance in the >2.5 eV region and the quantum yield of photoluminescence at ∼1.6 eV by ∼15 times.
