Owing to the existence of tetraarylethene (TAE) moiety in the chiral macrocycle, the aggregation-induced emission properties and solid-state emission for these chiral materials were further studied (Figure ). For conjugated macrocycles, they displayed classical AIE behavior with low emission intensity in THF and intense emission as nano-aggregates. Under low water content (f w ), these CCMs displayed very weak emission, for example, the absolute emission quantum yield (φ F ) for SBT-OMe and SBT-Br was recorded to be as low as 1.5% and 1.3% in pure THF. When the water content exceeded a threshold value, the emission intensity and lifetime of these CCMs dramatically raised owing to the formation of nanoaggregates (Figure and). For instance, the φ F for SBT-OMe and SBT-Br had increased to 42.1% and 42.8% in THF-H 2 O mixture (1/9). Interestingly, the emission wavelength for SBT-Br had obviously blue-shifted to 457 nm under f w = 60%, relative to the green emission at 485 nm when f w = 90%. This blue-shifted emission was proba-bly attributed to the formation of nano-crystals, which had been widely observed in the mechano-chromic luminescence for AIEgens. Notably, these four pairs of chiral macrocycles all exhibited bright blue or green emission with high φ F in solid state, as nano-aggregates, and in PMMA film as shown in Figure and Table .
