Hollow spheres self-assembled by a tetraphenylethylene macrocycle and their transformation to bird nests under ultrasound

Song, Song,Zheng, Yan-Song

supporting information, p. 820 - 823 (2013/03/29)

A new tetraphenylethylene macrocycle easily self-assembled into both intrinsic pores and extrinsic pores in crystal and hollow spheres in precipitates.
