Donor-acceptor crystals are of huge potential applications in the area of sensor, memory and radio frequency devices. In this work, we observed the stacking modes between poly (3-thiophene) and fullerene are mainly segregated-stacking and mixed-arrangement within crystals. Based on real-time structure analyses, poly (3-thiophene) and fullerene do not show crystallization initially in the solution state although there exists antisolvent. However, poly (3-thiophene) completed crystallization and demonstrated ordered nanowire structures after 90 min evolution, while, fullerene needs long time saturated evaporation to crystallize. In addition, the analysis of time dependent charge transfer process provides more information to further understand the crystallization dynamics. Therefore, revealing the nucleation and growth mechanism of organic charge transfer crystals and modifying the self-assembling processes will drive the development of a new class of organic nano electronics.

供体-受体晶体在传感器，存储器和射频设备领域具有巨大的潜在应用。在这项工作中，我们观察到聚（3-噻吩）和富勒烯之间的堆积模式主要是晶体内的隔离堆积和混合排列。根据实时结构分析，尽管存在反溶剂，但聚（3-噻吩）和富勒烯最初在溶液状态下不会出现结晶。然而，聚（3-噻吩）在90分钟的演化过程中完成了结晶并显示出有序的纳米线结构，而富勒烯需要长时间的饱和蒸发才能结晶。此外，时间依赖性电荷转移过程的分析提供了更多信息，可进一步了解结晶动力学。所以，
