FacilitatingJ-Aggregate Formation by LoweringActivation Energy to Achieve Ultrahigh Brightness for NIR-II FluorescenceImaging and Photoacoustic Imaging

Abstract Organic fluorophores operating in the second near-infrared window (NIR-II, 900–1700 nm) are plagued by low quantum yields (QYs) and diminished brightness in aqueous media. To address this challenge, we proposed a strategy of regulating the activation energy for aggregate...
