Blends consisting of two components, namely a liquid crystalline perylene ester and a bilaterally extended perylene ester, were studied. The liquid crystalline properties of these blends were investigated in detail by means of polarized optical microscopy and differential scanning calorimetry. The resulting phase diagram was used to explore the potential of these blends as emitter layers in OLEDs, which were prepared via thermal evaporation in a vacuum and spin coating of solutions.

两种Per衍生物的共混物：介晶性能及其在OLED中作为发射体的应用

研究了由两种组分组成的共混物，即液晶per酯和双向延伸的per酯。通过偏振光学显微镜和差示扫描量热法详细研究了这些共混物的液晶性质。所得相图用于探索这些共混物在OLED中作为发射极层的潜力，该层是通过在真空中进行热蒸发并旋涂溶液制备的。
