New hindered tetraphenylethylene (TPE) helicates with substitution at 2,6‐position of phenyl rings were designed and synthesized. Due to the increased hindrance, the TPE helicates emit strong deep‐blue to violet fluorescence both in the solid state and in solution, and could be resolved into enantio...
