Abstract

We determined the optimum dispersant to separate bulk Nb₂Se₉ material into 1D chain units. The Nb₂Se₉, which had a negative zeta potential (−43.3 mV), showed acidic characteristics and strongly bonded with the amine head of octadecyl amine through a charge transfer (from the amine to Se atoms) reaction. The steric hindrance of the octadecyl tail resulted in excellent dispersion of Nb₂Se₉ (down to nanometre-sized mono-chains).
