Hydroazaacene dicarboximide derivatives with red to NIR absorptions are designed and synthesized, which exhibit well-defined J-aggregation behaviors in both solution and thin films. The absorption and emission of an aggregate extend well into the NIR regime (λ(max) = 902 nm), manifesting particularly narrow bandwidth (fwhm = 152 cm(-1)) and is nearly transparent in the visible region.
设计并合成了具有红到近红外吸收的氢杂吖嗪二酰亚胺衍生物，它们在溶液和薄膜中表现出明确的 J-聚集行为。聚集体的吸收和发射延伸到近红外区域（λ(max) = 902nm），表现出特别窄的带宽（fwhm = 152cm(-1))，在可见光区域几乎透明。
