Turning-on the quenched fluorescence of azomethines through structural modifications

A series of fluorene azomethines were prepared to examine the effect of structural modification on the absolute fluorescence quantum yields (Φfl). The change in fluorescence occurring upon reversing the orientation of the azomethine bond, the number of fluorene units, and alkylation at the 9,9′-positions of fluorene was examined. It was found that Φfl could be tailored with these structural modifications with 0.05 ≤ Φfl ≤ 0.45. The highest Φfl was measured for the trimer derived from 2,7-diamino fluorene with each fluorene being alkylated at the 9,9′-positions. The fluorescence quantum yields did not increase at 77 K, implying the absence of fluorescence quenching modes involving internal conversion. Fluorescence enhancement was also not observed upon protonating the imine with trifluoroacetic acid. This confirms that Waldon inversion and isomerization are not fluorescence deactivation modes. Additionally, no photoisomerization was observed either at room temperature or at 77 K when the fluorene derivatives were irradiated at 354 nm. In contrast, the Z photoisomer of a N-benzylideneaniline analogue was spectroscopically detected both by absorbance and by 1H NMR spectroscopy. The absolute fluorescence quantum yield of conjugated azomethines was increased to 45 % by structural modifications and adjusting the orientation of the azomethines. Copyright

Systematic studies on mechanochemical synthesis: Schiff bases from solid aromatic primary amines and aldehydes

A versatile and robust mechanochemical route to Aldehyde–Schiff base conversions has been established for a broad range of aldehydes via a simple cogrinding in mortar with a pestle under a solvent-free, as well as solvent-assisted, environment. The extent

Effects of molecular conformation on the spectroscopic properties of 4,4′-disubstituted benzylideneanilines

The relationship between the molecular conformation and spectroscopic properties of unsymmetrical 4,4′-disubstituted benzylideneanilines, was explored by the combination of experiment and reference data. Crystal structure information and spectroscopic beh
