Abstract

Inspired by the formation of natural biominerals (e.g. bone and tooth), various sequence-defined synthetic molecules have been synthesized and exploited for the design and synthesis of functional hybrid materials. Here-in, we report the synthesis of a new type of sequence-defined two-dimensional nanocrystals from a series POSS-containing hybrid peptoids. These POSS-containing 2D hybrid materials are highly stable and exhibit an enhanced mechanical property. By varying peptoid side-chain chemistry, we further demonstrated that the accu-rate displacement of a large variety of function groups on the POSS-containing 2D nanocrystals and built a highly efficient Förster resonance energy transfer (FRET) system. We expect this type of hybrid 2D nanomaterials will offer unique opportunities for applications.
