Abstract:
Three arginine containing oligo borono peptides (BPs(1 3)) were synthesized by employing a standard FMOC chemistry SPPS. BPs(13) could spontaneously selfassemble into supramolecular architectures at a physiological environment. With recognition between BPs and alizarin red S (ARS), the fivemembered ring borate esters (ARS/BPs) could be formed with dramatic changes in fluorescent feature and visible color. These selfassembled supramolecular architectures were observed by scanning electron microscope (SEM) and their selfassembly mechanisms were explored by Fourier Transform Infrared Spectroscopy (FTIR) and Circular Dichroism (CD). It was found that BPs were capable of selfassembling into wellordered supramolecular architectures, and after recognition of ARS, ARS/BPs could further selfassemble into more ordered and sophisticated supramolecular architectures.
