Towards understanding the structural requirements for extending anodic reversibility, a series of conjugated azomethine triads end-capped with amides were prepared.
The absolute fluorescence quantum yield (Φfl) of a polyfluorenyl azomethine homopolymer was measured as function solvent polarity. induced and temperature dependent the were also investigated they compared to corresponding monomer copolymer. Φfl consistent (45-70%), regardless polarity with Stokes shifts up 7460 cm(-1) in ethanol. In contrast, its decreased from 60% ethanol 1% toluene, whereas < 5% for analogous copolymer measured. Moderate yields (Φfl ≈ 25%) possible thin film when...
A series of thiophenoazomethines connected to a central triphenylamine were prepared. The effect the type aminothiophene used prepare conjugated azomethines and number azomethine bonds, ranging from one three, flanking on spectral, electrochemical, spectroelectrochemical properties investigated. Both absorption fluorescence (6–8) derived 2,5-diaminothiophene (1) found be contingent azomethines. spectral red-shifted with increasing bonds. In contrast, (9–11) 2-aminothiophene (2) not perturbed...
Abstract The synthesis and characterization of six triarylisocyanurates, featuring 2,7‐fluorenyl or 9,10‐anthracenyl groups incorporated in their peripheral arms are reported. Photophysical studies reveal that these new octupolar derivatives more fluorescent ( Φ F ≥0.60 for all compounds except 1,3,5‐tri(9H‐fluoren‐2‐yl)‐1,3,5‐triazinane‐2,4,6‐trione 3 ) present a red‐shifted lowest absorption emission compared to known phenyl analogues comparable size. Depending on the nature terminal...
