Abstract

Herein, TLCP and TRCP denote the transmitted light intensities of
the UCPL film under illumination with LCP and RCP, respectively.
CD refers to the differential absorption between LCP and RCP. A
positive value of ΔT indicates that the film induces a left-handed
effect, whereas a negative value signifies a right-handed effect.
The same principle applies to the CD value. Typically, the CD
signal of strongly chiral materials reaches a magnitude of 1000
mdeg. As shown in Figure S9(B), the test results of the UCPL film
in this study exhibit almost no spectral fluctuations at this scale.
When the scale is magnified to that presented in Figure S9(C),
as evidenced by the curves, a sharp increase in the left-handed
effect emerges at approximately 390 nm and 540 nm; however,
the magnitude of this effect is extremely small, remaining below
4 mdeg in all cases. This can be identified as baseline noise,
confirming that the UCPL film exhibits no chiral characteristics.
