We determined the optimum dispersant to separate bulk NbSe material into 1D chain units. The NbSe, 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 NbSe (down to nanometre-sized mono-chains).
我们确定了将块状NbSe材料分离成一维链单元的最佳分散剂。具有负zeta电位（-43.3 mV）的NbSe表现出酸性特征，并通过电荷转移（从胺到Se原子）反应与十八烷基胺的胺头强烈结合。十八烷基尾部的空间位阻导致NbSe具有出色的分散性（低至纳米级单链）。
