Synthesis and ion-selective properties of an amphiphilic butadienyl dye
Abstract
The synthesised amphiphilic benzodithia-15-crown-5 butadienyl dye forms stable monolayers on distilled water (up to 47 mN m–1) and undergoes specific interactions (complex formation) with Hg2+ or non-specific interactions with K+, as follows from surface pressure – and surface potential – molecular area isotherms.
