A spread Langmuir film on the air/water interface can serve as a basic model for the understanding of organized molecular systems[1]. Generally, it is considered that only those compounds that possess simultaneously a hydrophilic head group and a long-alkyl chain can be spread on the air/water interface[2-4]. Therefore, researches on the organized molecular films are mainly concerned with typical amphiphiles. In order to expand the choice in molecular film to form materials and omit the tedious synthetic work on amphiphiles, we are trying to assemble organized molecular films using long alkyl-chain-free compounds[5,6]. Dithizone(DZ) is a well-known analytical reagent mainly noticed by analysts[7].
