Abstract
By introducing chiral leucine pendants to silole scaffold, leucine‐containing silole (Silole‐Leu) is synthesized and it is endowed with not only aggregation‐induced emission and circular dichroism, but excellent chiral polarized luminescence as well. Silole–Leu also has the capacity to self‐assemble into nano/micro helical luminescent fibers and the dimension of the fibers can be tuned by adjusting the ratio and volume of mixed solvents for evaporation as revealed by atomic force microscope, scanning electron microscope, and fluorescence microscope. The characteristic helicity of microfibers is directly visualized for the first time by using fluorescence microscope.
