ABSTRACT
Spin crossover complexes based on either iron(II) or iron(III) give a colorimetric response upon self-assembly with barbituric acids. They can be used as visible sensors for these narcotics, selectively detecting barbiturates in the presence of other biologically-relevant hydrogen bonding species.

ABSTRACT
Iron complexes derived from 6-diaminotriazyl-2,2'-bipyridines display spin crossover behaviour, and hydrogen bonding-controlled self-assembly with a suitable barbiturate partner can modulate the crossover from mixed low and high spin to high spin. This system is the first to use solution-phase self-assembly of complementary hydrogen-bonding organic species to modulate spin state.
