Engineering of aggregation-induced emission luminogens by isomeric strategy to achieve high-performance optoelectronic device

Achieving non-doped organic light-emitting diodes (OLEDs) with high electroluminescent (EL) performance is essential for both illumination source and display applications. A source of this difficulty is the aggregation-induce quenching effect of emitters

Triptycene-scaffolded tetraphenylethylenes with irregular temperature-dependence AIE

A series of new tetraphenylethylene monomer, dimer and three-dimensional trimer based triptycene-bridged triphenylethenes has been constructed. Their structures were clearly confirmed and the irregular fluorescent behaviors at different temperatures and s

Opposite ESIPT characteristic of two AIE-active isomers with different linkage sites

In this work, we report two isomers composed of 1-phenyl-1H-phenanthro[9,10-d]imidazole (PI), hydroxyl and tetraphenylethylene (TPE), abbreviated as m-PITPE and p-PITPE. It is found that they exhibit similar aggregation-induced emission (AIE) behavior but totally different excited-state intramolecular proton transfer (ESIPT) characteristic, as a result of the different linkage sites of PI on TPE moiety. Theoretical calculations and their different experimental responses to F? demonstrate that only the para-linkage isomer displays ESIPT. In m-PITPE with meta-linkage, the electron cloud distribution only locates at the TPE part in the singlet excited (S1) states, which results in the localized excited state without ESIPT characteristic.
