Synthesis and ion-selective properties of an amphiphilic butadienyl dye
摘要:
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.

Benzothiazole type butadienyl dyes containing a dithia‐15‐crown‐5 (2a) or dithia‐18‐crown‐6 ether (2b) moieties were synthesized. The structures of dyes 2a,b and their complexes with Ag+ and Pb2+ were studied by an X‐ray crystallography. It was found that the conformations of dithiacrown–ether moieties of dyes 2a,b are unfavorable for complex formation and change significantly upon binding of Ag+ or
