Ultrabright NIR-II fluorophores enabled by noncovalent conformational locking for in vivo inflammation imaging
Ultrabright fluorophores emitting in the second near-infrared (NIR-II, 1000–1700 nm) window are highly desirable for biomedical and optoelectronic applications but remain rare, because fluorescence brightness requires the simultaneous realization of a large absorption coefficient (ε) and a high photoluminescence quantu...
