Green synthesis and photophysical properties of novel 1H-imidazo[4,5-f][1,10]phenanthroline derivatives with blue/cyan two-photon excited fluorescence

A simple, rapid, and highly efficient method has been developed for the synthesis of a series of novel 1H-imidazo[4,5-f][1,10]phenanthroline derivatives (1BN, 2Py, 3BI, 4BT, and 5MOBI) via a three–component, one–pot reaction under solvent–free conditions.

Synthesis, dual fluorescence, and fluoroionophoric behavior of dipyridylaminomethylstilbenes

The synthesis, dual fluorescence, and fluoroionophoric behavior of two donor-σ spacer-acceptor (D-s-A) compounds, trans-4-(N,N-bis(2-pyridyl) amino)methylstilbene (1H) and trans-4-(N,N-bis(2-pyridyl)amino)methyl-4′- cyanostilbene (1CN), are reported and compared to that of trans-4-(N,N-bis(2- pyridyl)amino)methyl-4′-(N,N-dimethylammo)stilbene (1DPA). To gain insights into the dual fluorescence properties for 1H and 1CN in polar but not in nonpolar solvents, model compounds resulting from a replacement of the stilbene group by alkyl (2R) or xylyl (2X) groups or from a replacement of the dipyridylamino (dpa) group by dianisoleamino (3AA), diethylamino (SEE), methylanilino (3MP), or diphenylamino (3PP) groups also have been investigated. In addition to 1H and 1CN, all four compounds of 3 display dual fluorescence. The locally excited (LE) fluorescence mainly results from the stilbene group and the ICT fluorescence from the through-bond interactions between the amino donor and the stilbene acceptors. In the presence of transition metal ions such as Zn(II), Ni(II), Cu(II), and Cd(II), the ICT processes are switched from dpa → stilbene (A) in 1H and 1CN to stilbene (D) → dpa/metal ion (A) in their complexes. Whereas the ICT states for the complexes are generally nonfluorescent, an exception was found for the case of 1H/Zn(II). As a result, substituent-dependent fluoroionophoric behavior has been demonstrated by 1H, 1CN, and 1DPA in response to Zn(II).
