Effect of solvation on the aggregation-induced luminescence of tetraphenylethene derivatives†
Abstract
The compound TPE-(α-NH2)2 was synthesized. In the water-THF mixture (fw = 90%), a relatively stable non-emission aggregate with ultrasound-responsive emission properties could be obtained. It was found that the preferential solvation of THF plays an essential role in the emission properties through controlling the aggregation patterns.
