英文摘要: Abstract(#br)Subtle modification on molecular structure can play a crucial role in determining solid-state fluorescence properties and stimuli-responsive behaviors. In the current work, we utilize the condensation reactivity of benzaldehyde attached at the periphery of 1,4-diketopyrrolo[3,4-c]pyrrole (DPP) with benzil and phenanthrene-9,10-dione to design and synthesize two new DPP-centered A′‒A‒A′-type dyes (DPPBI and DPPPI), and they can be regarded as the analogues with and without the locked two peripheral phenyls. DPPBI and DPPPI show similar solution optical properties, however, their pristine solids emit bright yellow (570 nm) and near-infrared (NIR, 685 nm) fluorescence, respectively, indicating that the tiny structure change can induce a remarkable aggregate emission difference...
