Abstract / Description:The anion-capped amphiphilic benzodithia-18-crown-6 styryl dye forms relatively stable insoluble monolayers on distilled water (collapse pressure is 25.5 mN m(-1)) and aqueous solutions containing alkali (25.3-26.4 mN m(-1)) and heavy metals (49.0 mN m(-1) for Ag+). Two types of the dye monolayer structures (depending on alkali metal or heavy metal cations present in the aqueous subphase) have been discriminated from surface pressure-molecular area and surface potential-molecular area isotherms, The ionoselective and photosensitive properties of the amphiphilic dye in monolayers have been studied in the presence of K+, Na+, Mg+, Ca+ or Ag+ cations in the aqueous subphase.
