우리는 α-페닐-4'-(디페닐아미노)스틸벤(TPA) 단결정의 제조와 정공 수송 특성 평가에 대해 설명합니다. 광학현미경, 편광현미경, X-선 회절을 이용한 특성화를 바탕으로 TPA의 용해도 및 과용해성 곡선을 기반으로 한 용액법을 사용하여 7.0×0.9×0.8mm 크기의 대규모 TPA 단결정을 성공적으로 합성했습니다. 특히, 장축 방향의 전류는 단축 및 두께 방향의 전류보다 크다(i(긴) > i(짧은) > i(두께)) 이는 TPA 단결정의 이방성 전하 이동을 나타냅니다. 관찰된 이방성 전도성은 TPA 단결정의 트리페닐아민 단위의 방향으로 잘 설명됩니다. 또한, TPA 단결정의 장축 방향의 활성화 에너지는 TPA의 단축 방향과 α-페닐-4'-[비스(4-메틸페닐)아미노]스틸벤의 모든 축의 활성화 에너지보다 낮다. 이전 연구에서 보고된 단결정.

Abstract: We describe the preparation of an α-phenyl-4'-(diphenylamino)stilbene (TPA) single crystal and the evaluation of its hole transport property. Based on the characterization using optical microscopy, polarizing microscopy, and X-ray diffraction, a large-scale TPA single crystal of dimensions 7.0×0.9×0.8mm is successfully synthesized using a solution method based on the solubility and supersolubility curves of the TPA. Notably, the current in the long-axis direction is larger than those in the short-axis and thickness directions (i(long) > i(short) > i(thickness)), which reveals the anisotropic charge transfer of the TPA single crystal. The observed anisotropic conductivity is well explained by the orientation of the triphenylamine unit in the TPA single crystal. Furthermore, the activation energy of the long-axis direction in the TPA single crystal is lower than that of the short-axis in TPA and all the axes in the α-phenyl-4'-[bis(4-methylphenyl)amino]stilbene single crystal reported in our previous study.
