In this work, a AIE-active tetraphenylethylene derivative consist of long carbon chain and bromo group have been successfully synthesized. This compound only faintly emit in solution but show strong emission in aggregated state. The photoluminescence progressively increases during increasing the water content. In the THF/water mixture with 90 % water, the photoluminescence intensity is about 16 times increased if compared to pure THF. On the other hand, we observed that the particles are aggregated in the THF/water mixture with 60 % water. This result can be provided to associate with AIE-active.
