1. Estudo de um sensor cromogênico aniônico fundamentado na competição entre uma merocianina e um ânion pelo calix[4]pirrol
This work has studied the assembly of a chromogenic sensor that uses as receptor calyx[4]pyrrole (CP), which is capable to recognize fluoride with high efficience, and two solvatochromic dyes, Brookers merocyanine (MB) and Reichardts dye (CR), as signalizing unity. The solutions of MB in acetonitrile, a low polarity medium, exhibit violet color. It was obser
