具有l型辛胺、l型氨或z型Cd（油酸酯）2配体的玻尔锌矿CdSe量子带被交换为几种金属-二硫代氨基甲酸酯配体[M(S2CNR1R2)2]: Cd(S2CNPhMe)2、Cd(S2CNEt2)2、Zn(S2CNPhMe)2和Zn(S2CNEt2)2。所有的M(S2CNR1R2)2化合物都在{CdSe[Cd（油酸酯）2]0.19}量子带（qb）中成功交换了配体，这引起了配体交换qb吸收光谱的类似光谱位移。光谱数据、实验测定的晶格应变以及配体与[Na][Et2NCS2]和[NH4][MePhNCS2]的交换表明，[M(S2CNR1R2)2]配体与(S2CNR1R2)−基团直接连接到QB表面，[M(S2CNR1R2) +基团作为电荷平衡离子对的x型配体结合。x型二硫代氨基甲酸酯配体对CdSe qb没有任何特殊的电子效应。
Wurtzite CdSe quantum belts with L-typen-octylamine, L-type ammonia, or Z-type Cd(oleate)2ligands are exchanged for several metal-dithiocarbamate ligands [M(S2CNR1R2)2]: Cd(S2CNPhMe)2, Cd(S2CNEt2)2, Zn(S2CNPhMe)2, and Zn(S2CNEt2)2. Successful ligand exchange with all M(S2CNR1R2)2compounds occurs from {CdSe[Cd(oleate)2]0.19} quantum belts (QBs), which induce similar spectral shifts in the absorption spectra of the ligand-exchanged QBs. Spectroscopic data, experimentally determined lattice strains, and ligand exchanges with [Na][Et2NCS2] and [NH4][MePhNCS2] establish that the [M(S2CNR1R2)2] ligands bind as bound-ion-paired X-type ligands with (S2CNR1R2)−groups ligated directly to the QB surfaces and [M(S2CNR1R2)]+groups serving as the charge-balancing ion-paired countercations. The X-type dithiocarbamate ligands do not impart any special electronic effects to the CdSe QBs.
