Sensitization of Near-Infrared-Emitting Lanthanide Cations in Solution by Tropolonate Ligands

摘要

The quest for luminescent reporters that emit in the near-infrared(NIR)domain is a target of prime importance,as NIR photons can penetrate deep into tissues without causing damage and without significant loss of intensity owing to the low absorption of NIR photons in such media.Furthermore,the use of NIR light is one of the best strategies to obtain high-resolution pictures of deep tissues,as NIR light diffracts much less than visible light(diffraction is proportional to 1/(lambda)~SP,SP = scattering power).
