A new synthetic route to prepare II–VI nanoscale materials, such as CdS nanorods and ZnSe nanoparticles is demonstrated and the advantage of using nonionic triblock copolymer systems,i.e., H (– OCH 2 CH 2)x[– OCH ( CH 3)– CH 2]y(– OCH 2 CH 2)y– OH , or ( EO )x( PO )y( EO )x as structure-directing agents in the synthesis of low dimension nanomaterials is introduced. The effect of (EO)/(PO) ratio in controlling the diameter and the morphology of the final product is addressed. The employ of F127 [( EO )106( PO )70( EO )106] as a surfactant-template to study the temperature-dependent size-selection of ZnSe nanoparticles is also presented. We observe that the larger ZnSe nanoparticles are arrested first by the hydrophilic fractions of triblock copolymers F127, while the smaller particles still remain their thermal motion in the aqueous phase.
