Near-infrared (NIR, 700-1600 nm) emitting lanthanide complexes offer great advantages over the conventional visible light emitting materials for bioimaging and sensing due to the deep penetration of NIR light in the biological fluids and low bleaching effect to the substrates. However, the application has been hampered by their poor NIR emission efficiency and the requirement of short excitation wavelengths. The porphyrin and BODIPY dyes are excellent chromophores with great potential to address these issues due to their unique photophysical properties and structural functionalities. In this review, our recent investigation on synthesis, structural analysis and photophysical properties of their lanthanide complexes is summarized and some important findings are highlighted. We focused on the synthesis and structural characterization of Yb3+, Nd3+ and Er3+ complexes of porphyrin and BODIPY dyes and the impact of structural changes on the NIR emission efficiency. Sensitization mechanism in these complexes is also discussed.
