Self-assembly of trigonal building blocks into nanostructures: molecular design and biomedical applications

Abstract

Trigonal molecules have a special triskelion structure similar to clathrin protein, providing great inspiration for constructing artificial nanoassemblies. To date, various synthetic trigonal conjugates have been designed for supramolecular self-assembly, which have demonstrated versatile and controllable self-assembly ability in materials science. Here we will review the design of trigonal (sometimes called three-legged, tripodal, C₃-symmetric, or triskelion) building blocks that can self-assemble into various nanostructures and discuss the biomedical applications of the self-assembled nanomaterials.
