Here, we describe a rapid and efficient synthetic method of peptide-conjugated perylene diimide (P-PDI) using solid-phase peptide synthesis (SPPS). Due to severe insolubility of perylene dianhydride (PDA) as a starting material of perylene diimide (PDI), PDA was initially conjugated with amino acids to obtain soluble PDI derivatives. Target peptides were synthesized on a 2-chlorotrityl chloride resin using the SPPS method and then conjugated with the amino acid-appended PDI.

Article Synopsis
  • Self-assembled nanostructures made from tyrosine-rich peptides have useful applications in biocatalysis, organic films, and membranes.
  • The study focuses on controlling the self-assembly of a specific peptide sequence (YYACAYY) to create large, thick nanofilms using Langmuir-Blodgett and Langmuir-Schaefer techniques.
  • The Tyr-C7mer peptide demonstrated surfactant-like behavior, enabling the successful creation and characterization of uniform nanofilms with redox properties, facilitated by silver nanoparticles assembly without additives.
