Transcription of gel assemblies of bola type bis(oxalamide)-dicarboxylic acid and -diester gelators into silica nanotubes and ribbons under catalyzed and non-catalyzed conditions

Abstract

Assemblies of the bola type bis(oxalamide)-dicarboxylic acid and -diester gelators lacking any positive charges or amine groups can be transcribed into silica nanotubes and ribbons by sol-gel polymerizations of tetraethoxysilane (TEOS) either in the presence or absence of benzyl amine as solution catalyst
