RESUMEN
A new pyrene-based derivative bearing an azadiene group was synthesized as a ratiometric chemosensor for Hg(2+) in aqueous acetonitrile solution. The "off-on" type signaling behavior of the fluoroionophore is due to the metal ion induced conformational changes from the weak pyrene monomer emissions to strong pyrene excimer emission.

RESUMEN
In the title compound, C(26)H(18)N(4), each ring is almost planar with maximum deviation of 0.012â (5)â Å. In the crystal, mol-ecules are stacked by weak C-Hâ¯π inter-actions, forming a three-dimensional framework.
