Rational design of NIR-emitting iridium(iii) complexes for multimodal phosphorescence imaging of mitochondria under two-photon excitation†
Abstract
A series of NIR-emitting iridium(III) complexes were developed for multimodal phosphorescence imaging (NIR imaging, phosphorescence lifetime imaging and time-gated imaging) of mitochondria in living cells, 3D multicellular spheroids (MTCCs) and hippocampus slice under two-photon excitation.
