Origins of Selectivity in a Colorimetric Charge-Transfer Sensor for Diols

Origins of Selectivity in a Colorimetric Charge-Transfer Sensor for Diols

Bispyridyl hydrogen bonding receptor 1 forms colored charge transfer (CT) complexes with complementary phenols and naphthols. Despite its low association constants of ∼101 M−1, receptor 1 was highly selective forming CT complexes of varying color and intensity with different diol guests. The selecti...

description Bispyridyl hydrogen bonding receptor 1 forms colored charge transfer (CT) complexes with complementary phenols and naphthols. Despite its low association constants of ∼101 M−1, receptor 1 was highly selective forming CT complexes of varying color and intensity with different diol guests. The selectivity of 1 was correlated with the ability of its CT band to simultaneously yield information about the association constant and the electronic structure of the phenols and naphthols.
