摘要

Two new blue luminogens, Py-4MethylTPE and Py-4mTPE, constructed with a pyrene core and tetraphenylethene peripheries, have been successfully obtained. These two luminogens show AIE and AEE effects, respectively, as a result of minor differences in their structures. An OLED device based on Py-4mTPE exhibits a good performance (eta(C,max)=4.02 cdA(-1), lambda(EL,max)=436 nm) and reveals the powerful effect of a different linkage mode for the construction of blue AIE luminogens.
