The development of high-performance electro-optic materials is essential for optical communication technologies. In this study, the electro-optic properties of 2-ethylanilinium chloride (2EAC), a chiral and polar organic single-crystalline fiber material, were investigated. The Pockels effect was evaluated using a polarization-rotation measurement method. Clear linear dependences of the polarization rotation angle on the applied electric field were observed at incident polarization angles of 45° and 135°, consistent with theoretical predictions. Based on theoretical analysis, the effective electro-optic coefficient was estimated to be 12.7–15.4 pm/V. These results demonstrate the Pockels effect in 2EAC and suggest its potential as a promising organic electro-optic material.
