title: Chirality sensing by a fluorescent binaphthocrown ether-polythiophene conjugate.
abstract: Chiral recognition abilities of the title host for (R)- and (S)-α-methyl-4-nitrobenzylamine were examined in the ground and excited states to give a relative affinity (K(R)/K(S)) of 2.16 by spectral titration and a relative rate constant (k(R)/k(S)) of 2.23 by fluorescence quenching, revealing that the quenching process is static and not enantiodifferentiating.
