The present invention generally relates to stable emissive aggregates of polymers. The aggregates are composed of various polymer molecules arranged in such a way as to allow extended electronic couplings between nearby polymer molecules, enhancing exciton transport, while minimizing the effects of quenching due to interchain interactions. For example, the polymer molecules may be arranged in a non-aligned, electronically-communicative manner (for example, at an oblique angle), stabilized by various methods such as chemical linkages or physical interactions. Within the aggregate, electronic interactions along the polymer molecule may extend to nearby polymer molecules, which may be observed as a shift in the absorption spectra relative to a random dispersion. Light emitted from the aggregate may be polarized in some cases, for example, linearly or circularly, which may be caused by chiral arrangements of polymers within the aggregate (the polymers themselves may or may not be chiral). These aggregates may find widespread use, for example, in enantiomeric detectors, electrochemical devices, photodetectors, organic diodes, sensors, light sources, or photovoltaic devices.
本发明一般涉及聚合物的稳定发射聚集体。聚合体由各种聚合物分子组成,其排列方式可使附近的聚合物分子之间产生扩展的电子耦合,从而增强激子传输,同时将链间相互作用导致的淬火效应降至最低。例如,聚合物分子可以不对齐、电子通信的方式排列(例如,以斜角排列),并通过
化学连接或物理相互作用等各种方法加以稳定。在聚合体内部,沿着聚合物分子的电子相互作用可能会延伸到附近的聚合物分子,这可以通过相对于随机分散的吸收光谱偏移来观察。聚合体发出的光在某些情况下可能会偏振,例如线性偏振或环形偏振,这可能是由于聚合体中聚合物的手性排列(聚合物本身可能是手性的,也可能不是)造成的。这些聚合体可广泛应用于对映体检测器、电
化学装置、光检测器、有机二极管、传感器、光源或光伏装置等。
