AB  - The core of aggregation-induced emitting (AIE) molecules was their aggregation 
      behavior. It was, in essence, a self-assembly process driven by noncovalent 
      interactions, which were governed not only by the chemical structures of the 
      molecules but also by the conditions where the self-assemblies were formed. The 
      self-assemblies of two AIE molecules, tetraphenylethene (TPE) derivatives 
      carrying one valine attachment (TPE-Val) and two valine attachments (TPE-2Val), 
      were studied. Both kinds of molecules self-assembled into supramolecular helical 
      fibers with different handedness upon the addition of poor solvent to their 
      solution. However, when deposited on air/water interface, both kinds of molecules 
      formed aligned elementary helical fibers instead of supramolecular fibers. The 
      lateral solvophobic effect exerted by water molecules caused a shift of the 
      original noncovalent balance between molecules and solvent; thus, the 
      supramolecular helical assemblies were unraveled into aligned helical elementary 
      fibers. Similar elementary assemblies were formed on the surface of 3-aminopropyl 
      triethoxysilane-modified mica, confirming the lateral solvophobic effect on the 
      self-assemblies of the molecules.
