might further profit the (I L À I R ) values. In addition, the total fluorescence intensity
(I L + I R ) decreased after adding benzoic acid. Based on the g lum ¼ 2 Â (I L À I R )/
(I L + I R ), an amplification of the CPL resulted from lower (I L + I R ) values could be
observed.
11.3.2.2 Aggregation-Induced Emission (AIE) Triggered CPL in Gels
As stated above, the regulated assembly of chiral emitters would be one of the
general and simple ways adopted for enhancing g lum . However, due to the
aggregation-caused quenching (ACQ) effect, which leads to a much lower or
