Abstract Organic optical waveguide materials have attracted considerable attention for their promising applications in photonic and optoelectronic devices. However, most materials, excellent light‐loss properties at high temperature cannot be obtained due to many factors. Consequently, realizing efficient that perform well elevated temperatures remains a significant challenge. In this study, relying on the luminescent self‐assembly of liquid crystals (LLCs), successfully fabricated are present highly active waveguides. A systematically synthesized set LLCs with different structures is named according substituent type position cyano group, namely α‐DECN, α‐DEEOCN, β‐DECN, β‐DEEOCN. Notably, α‐DECN β‐DECN reveal hexagonal columnar phase, while α‐DEEOCN β‐DEEOCN exhibit smectic phase. Optical experiments revealed showed behavior, where lowest light loss reached 0.15 dB mm −1 room temperature. Remarkably, these show even lower temperatures, reaching 0.11 as point. Further experimental results indicate phenomenon attributed change dipole moment molecules. This research forms groundwork advanced exploration material.
