摘要

Abstract

Nonreciprocal chiroptical response

a phenomenon arising from light-matter interaction by the coupling of linear optical effects

attracts rapidly increasing attention to advance fundamental chiroptical theory and develop high-performance optical devices. Herein

we fabricated a chiral polyurethane system with tunable apparent all-angle nonreciprocal chiroptical response

where can be further controlled by modulating the content of doped small molecules within the polyurethane film. Building on these observations

we investigated the origins of the angle-dependence and nonreciprocal chiroptical responses

and proposed a plausible mechanism to explain the emergence of this apparent circular dichroism (CD) signal. Furthermore

we utilized achiral helical polyacetylene to regulate the response wavelength. Our research establishes a clear relationship between polyurethane structure and apparent all-angle nonreciprocal chiroptical response

providing new insights into the connection between chiral materials and linear optical materials.
