title: [2,2'-Bipyridyl]-3,3'-diol as a molecular half-subtractor.
abstract: [structure/diagram: see text] Spectral responses at two different wavelengths revealed that BP(OH)2 ([2,2'-bipyridyl]-3,3'-diol) can function as a combinatorial logic circuit for a molecular half-subtractor with acid and base as input variables.
