In this paper, tetraphenylethylene (TPE) units, one of the
typical aggregation-induced emission (AIE) moieties, are utilized to construct a new functional
polyfluorene (PF) P1, which exhibited the exciting property of the aggregation-induced emission
enhancement (AIEE), instead of the aggregation-caused quenching (ACQ) of normal PFs, and could
probe the explosive with high sensitivity both in the nano-particles and solid state. Three other
TPE-containing polymers, P2-P4, were also successfully prepared, and demonstrated good
performance as explosive chemosensors and light-emitting materials. P3, bearing carbazole as
hole-transporting units showed the best performance with a maximum luminance efficiency of 1.17
cd/A and a maximum brightness of 3609 cd/m(2) at 12.9 V in its light-emitting diode device. (C)
