Ethyl 2-cyano-3-(4-(1,2,2-triphenylvinyl) phenyl) acrylate
(TPE-SKJ),
a newly synthesized luminogen based on tetraphenylethene, with single
crystal analysis exhibits photophysical phenomena such as aggregation-induced
emission (AIE); reversible mechanochromic, solvatochromic, organic
light emitting diode; and chemical sensing in aqueous media with great
selectivity and a low limit of detection. The synthesized material
demonstrates high selectivity and sensitivity capacity for sensing
MnO4
– in mixed aqueous media (water/acetonitrile,
v/v, 9/1). The detection limit for MnO4
– was found to be 0.086009 μg mL–1 with a
quantum yield (Φ) of 11%. Moreover, we employed TPE-SKJ material
in an organic light-emitting diode (OLED) as an emissive layer. The
device shows a maximum of 1.62% external quantum efficiency, higher
than nondoped emitting layer-based green OLEDs. The present results
will encourage ongoing research into the design of novel stimuli-responsive
organic materials with switchable properties based on their supramolecular
interactions for numerous applications.
