A bidentate borane as colorimetric fluoride ion sensor
Chem. Commun., 2004The bright yellow bidentate diborane (3), obtained by reaction of 10-bromo-9-thia-10-boraanthracene (1) with dimesityl-1,8-naphthalenediylborate (2), serves as a colorimetric anion sensor and selectively complexes fluoride with an association constant greater than 5 × 109 M−1 in THF.
