In this research, a recyclable ordered necklace-like "trimeric-DDSQ"-PDMS polysiloxane (DDDP) is presented. Specific bifunctional organosilicon building blocks, namely vinyl-terminated double-decker silsesquioxane (DDSQ-Vi), hydrogen-terminated double-decker silsesquioxane (DDSQ-H), and the dumbbell-shaped precursor (DPD), are fabricated. Stepwise polymerization from DPD precursor enables the synthesis of ordered necklace-like DDDPs. In this way, no additional purification or separation steps are necessary. DDDP contains a high proportion of nanocage-shaped DDSQ within its organosilicon backbone. This structure endows DDDP with outstanding thermal stability, optical transparency, favorable mechanical characteristics, and recyclability. These properties highlight the potential of DDDP in applications such as electronic circuit packaging and material recycling.

Construction of well-ordered two-dimensional (2D) and three-dimensional (3D) assemblies using one-dimensional (1D) units is a hallmark of many biointerfaces such as skin. Mimicking the art of difunctional properties of biointerfaces, which skin exhibits as defense and shelter materials, has inspired the development of smart and responsive biomimetic interfaces. However, programming the long-range ordering of 1D base materials toward vigorous control over 2D and 3D hierarchical structures and material properties remains a daunting challenge.

Rational design of plasmonic colloidal assemblies via bottom-up synthesis is challenging but would show unprecedented optical properties that strongly relate to the assembly's shape and spatial arrangement. Herein, the synthesis of plasmonic cyclic Au nanosphere hexamers (PCHs) is reported, wherein six Au nanospheres (Au NSs) are connected via thin metal ligaments. By tuning Au reduction, six dangling Au NSs are interconnected with a core hexagon nanoplate (NPL).
