Abstract

A series of structural complementary decapeptides with phenyl boronic acid tails or borono‐decapeptides (BPs) were designed and synthesized for supramolecular self‐assembly. After dissolving these borono‐decapeptides in deionized (DI) water, well‐defined nanofibers were formed in BP1 (B(OH)~2~VEKELVKEKL‐OH) and BP3 (B(OH)~2~AELELARARL‐OH). It was found that the self‐assembled borono‐decapeptide BP1 and BP3 have a parallel β‐sheet conformation in the formed nanofibers. The strategy demonstrated here shows a great prospect in preparation of well‐ordered nanofibers via rationally designing the molecular structures of peptides.

## Abstract **Summary:** Polyaniline (PANI)/Au composite nanotubes and nanofibers are synthesized through a self‐assembly process in the presence of camphorsulfonic acid and hydrochloric acid, as dopants, respectively. The PANI/Au composites are characterized by FT‐IR, UV‐vis, and thermogravimetric
