Rational design of selective and sensitive 'off-on' fluorescent probes for Zn(II) cations exploiting both PET and ICT mechanisms of sensing is illustrated by the synthesis and application of 5-aryl-2,2'-bipyridines modified with a dipicolylaminomethyl fragment. The aryl substituent provides tuning of the properties.
