虽然聚合物作为低成本、机械柔性、轻质的大面积光致发光器件和发光器件（OLED）具有显著的潜力，但它们的性能关键取决于对纳米尺度上的形态的理解和控制。CA。激子扩散的10 nm长度尺度设定了影响光致发光中的电荷分离和总效率所必需的图案化长度尺度。此外，大多数有机材料中电子和空穴迁移率的不平衡使得在许多器件架构中需要使用多个组件。在大面积溶液处理的器件中对10 nm长度尺度图案化的这些要求表明，以前用于更经典的绝缘聚合物系统的嵌段共聚物策略在有机电子学中可能非常有用。这一观点试图描述的有机光电子嵌段共聚物的合成和自组装。这些固有复杂的有源层的器件特征仍然是一个标志..
While polymers hold significant potential as low cost, mechanically flexible, lightweight large area photovoltaics and light emitting devices (OLEDs), their performance relies crucially on understanding and controlling the morphology on the nanometer scale. The ca. 10 nm length scale of exciton diffusion sets the patterning length scale necessary to affect charge separation and overall efficiency in photovoltaics. Moreover, the imbalance of electron and hole mobilities in most organic materials necessitates the use of multiple components in many device architectures. These requirements for 10 nm length scale patterning in large area, solution processed devices suggest that block copolymer strategies previously employed for more classical, insulating polymer systems may be very useful in organic electronics. This Perspective seeks to describe both the synthesis and self-assembly of block copolymers for organic optoelectronics. Device characterization of these inherently complex active layers remains a sign...
