Temperature-responsive luminescent solar concentrators (LSCs) have been fabricated in which the Förster resonance energy transfer (FRET) between a donor-acceptor pair in a liquid crystalline solvent can be tuned. At room temperatures, the perylene bisimide (PBI) acceptor is aggregated and FRET is inactive; while after heating to a temperature above the isotropic phase of the liquid crystal solvent, the acceptor PBI completely dissolves and FRET is activated. This unusual temperature control over FRET was used to design a color-tunable LSC. The device has been shown to be highly stable towards consecutive heating and cooling cycles, making it an appealing device for harvesting otherwise unused solar energy.
温度响应型发光太阳能集中器（LSCs）已经被制备出来，其中在液晶溶剂中供体-受体对之间的Förster 共振能量转移（FRET）可以被调节。在室温下，苝二酰亚胺（PBI）受体聚集并且 FRET 不活跃；而当加热到高于液晶溶剂各向同性相的温度时，受体 PBI 完全溶解并且 FRET 被激活。这种对 FRET 的不寻常的温度控制被用于设计一种可调谐颜色的 LSC。该器件在连续的加热和冷却循环中表现出高度的稳定性，使其成为一种有吸引力的用于收集否则未被利用的太阳能的器件。
