Two slightly twisted A-π-D-π-A molecules were prepared to demonstrate that the red/near-infrared mechanoresponsive luminescence turn-on behaviors could be realized through mechanically disturbing their weakly/non-emissive metastable nanostructures, giving emissive amorphous aggregates with λ = 620 nm, Φ = 12% (h-DIPT) and λ = 700 nm, Φ = 10% (DIPT), respectively.
制备了两个略微扭曲的A-π-D-π-A分子，以证明通过机械扰动其弱发射/非发射亚稳态纳米结构，可以实现红/近红外机械响应发光开启行为，分别得到发射波长为λ = 620 nm、荧光量子产率为Φ = 12%（h-DIPT）和λ = 700 nm、Φ = 10%（DIPT）的发光无定形聚集体。
