Urea-based constructs readily amplify and attenuate nonlinear optical activity in response to H-bonding and anion recognition.

چکیده
Urea-based molecular constructs are shown for the first time to be nonlinear optically (NLO) active in solution. We demonstrate self-assembly triggered large amplification and specific anion recognition driven attenuation of the NLO activity. This orthogonal modulation along with an excellent nonlinearity-transparency trade-off makes them attractive NLO probes for studies related to weak self-assembly and anion transportation by second harmonic microscopy.

Quinoline Based Bis-urea Receptors for Anion Binding and Selectivity: a Comparative Study
Abstract: Anions play an important role in a wide range of chemical and biological processes. Extensive attention has been focused on the design of hosts that can recognize and sense anion species selectively. Such recognition behavior can be monitored through optical, electrochemical, and fluorescence responses. The binding of an anion with a synthetic receptor is typically labile and reversib...

The optimized structures of studied compounds 23-28 are non planner with the two phenyl at C3 and C9 are out of the molecular plane of thiazolo[3,2-a]pyridine as indicated from a dihedral angles of 710 and 1160 respectively, using DFT-B3LYP method with 6-311G(d,p) as basis set. The natural bonding orbital (NBO) analysis of the parent molecule 23 have been analyzed in terms of the hybridization ...
متن کاملFluoride Anion Recognition by a Multifunctional Urea Derivative: An Experimental and Theoretical Study
In this work we demonstrate the ability of a multifaceted N,N'-disubstituted urea to selectively recognize fluoride anion (F(-)) among other halides. This additional function is now added to its already reported organocatalytic and organogelator properties. The signaling mechanism relies on the formation of a charge-transfer (CT) complex between the urea-based sensor and F¯ in the ground state ...
متن کاملLanthanide luminescent anion sensing: evidence of multiple anion recognition through hydrogen bonding and metal ion coordination.
The delayed lanthanide luminescence of the terbium [Tb(III)] diaryl-urea complex 1xTb is significantly enhanced upon sensing of dihydrogenphosphate (H2PO4(-)) in CH3CN, which occurs through multiple anion binding through hydrogen bonding interactions and potential metal ion coordination to Tb(III).
متن کاملHigh Affinity Carboxylate Binding Using Neutral Urea-Based Receptors with Internal Lewis Acid Coordination.
Uncharged receptors for anions and cations have many potential applications ranging from membrane transport carriers for ion-selective electrodes to reaction catalysts.1 As a consequence, there is a need to design and synthesize neutral receptors with high binding affinities and/ or high binding selectivities. Unlike cation receptors, there are essentially no examples of biotic, low molecular w...
