Heterocyclic selenium compounds were synthesized and their selfassembled monolayers (SAMs)on gold surface were reported.The heterocyclic selenium compounds are 4,5benzopiazselenole (BP) and anthra selenadiazol6,11dione (AS).The cyclic voltammetry results showed that the peaks of the oxidation and reduction of Fe(CN)3/46 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 Na2B4O7 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 Na2B4O7ethanol solution,and the course was cortrolled by adsorption.
Under microwave radiation conditions,a series of heterocyclic aromatic selenium compounds of 2,1,3-benzoselena-diazole(BS);1,2,5-selenadiazolo[3.4-b]pyridine(SPb);5-methy1-2,1,3-benzo-[3,4-c]selenadiazole(MB);5,7-dihydroxy-1,2,5-selenadiazolo-[3,4-d]pyrimi dine(DHSP)and 2,1,3-naphtho-[2,3-c]selenadiazole(NS) were synthesized with their respective ortho-aromatic diamines and selenium dioxide,and their yields were between 29% and 84%.The products obtained from the microwave solid-state reactions were characterized by IR,XRD,UV,FS and EA.
