An anionic gelator, D-C12ValC10COONa, derived from D-valine can cause physical gels in water and organic solvents. Helical 4,4(')-biphenylene-silica nanotubes and nanoribbons were prepared using it with 3-aminopropyltrimethoxysilane as a co-structure-directing agent and 4,4(')-bis(triethoxysilyl)-1,1(')-biphenyl (BTESB) as precursor. It was found that
