摘　　要：Heterocyclic selenium compounds were synthesized and their selfassembled monolayers (SAMs)on gold surface were reported.The heterocyclic selenium compounds are 4,5benzopiazselenole (BP) and anthra selenadiazol6,11dione (AS).The cyclic voltammetry results showed that the peaks of the oxidation and reduction of Fe(CN)3/46 almost disappeared after the Au electrode was covered by a monolayer of BP due to forming of SAMs,but AS did not.The reduction peak potentials of the BP and AS were 663mV and 659mV,respectively,in the Na2B4O7 solution with the modified gold electrode,while the reduction peaks potential of the BP and AS were 633mV and 704mV,respectively,with bare gold scanning in Na2B4O7ethanol solution,and the course was cortrolled by adsorption.Heterocyclic selenium compounds were synthesized and their selfassembled monolayers (SAMs)on gold surface were reported.The heterocyclic selenium compounds are 4,5benzopiazselenole (BP) and anthra selenadiazol6,11dione (AS).The cyclic voltammetry results showed that the peaks of the oxidation and reduction of Fe(CN)3/46 almost disappeared after the Au electrode was covered by a monolayer of BP due to forming of SAMs,but AS did not.The reduction peak potentials of the BP and AS were 663mV and 659mV,respectively,in the Na2B4O7 solution with the modified gold electrode,while the reduction peaks potential of the BP and AS were 633mV and 704mV,respectively,with bare gold scanning in Na2B4O7ethanol solution,and the course was cortrolled by adsorption.
