title: Tetracyanoresorcin[4]arene ion channel shows pH dependent conductivity change.
abstract: A pH sensitive artificial ion channel, tetracyanoresorcin[4]arene, whose pK(a1) to pK(a3) are around pH 7, was synthesized. Conductivities for potassium ion were increased by the progress of dissociation at the channel mouth.
