Perylene diimide derivative regulate the antimony sulfide morphology and electrochemical sensing for hydrazine

Abstract Sb 2 S 3 /perylene diimide derivatives composite micro-spheres composed of slight dendrites were synthesized by solvothermal reaction. Perylene diimide derivative with two carboxyl groups at amine position as morphology-controlling reagent is the key factor for determining the microscopic morphology of Sb 2 S 3 in this system. Time-dependent experiments have been conducted to track the formation of Sb 2 S 3 micro-spheres. Moreover, the composite material showed an excellent sensitivity of 29.8 μA mM −1  cm 2 with a low detection limit of 50 pM, it also showed better stability and selectivity in hydrazine detection. This approach not only regulate the morphology and composition of Sb 2 S 3 submicron materials effectively, but also provide new ideas for the manufacture of metal sulfide- perylenediimide amino acid derivative materials, which will be suitable for sensing, catalysis, and photovoltaic applications.
