Biocompatible MOFs with high absolute quantum yield for bioimaging in the second near infrared window

Here we detail a study highlighting the correlation between particle size and absolute quantum yield (QY) in novel mixed metal near-infrared (NIR) emitting metal–organic frameworks (MOFs) materials. The nanoscale analogue in this series presents a QY of 6.3%, the highest of any NIR emitting MOFs reported to date.
