Bis(isoquinoline N-oxide) pincers as a new type of metal cation dual channel fluorosensor.

Daniel Collado et al.

Organic letters, 4(5), 855-858 (2002-03-01)

[structure: see text] A new type of donor-spacer-acceptor podand system has been synthesized and proved as an efficient dual channel fluorosensor for Li+, Mg2+, and Ca2+. The known ability for the N-oxide function to bind Lewis acids is the key
