Study on Heterodinuclear plex Probe for Detecting Hypoxia Abstract
Molecular Oxygen(dioxygen)is one ofthe pivotal metabolites in anisms,and is imperative for maintaining the vital activity in almost all living deprivation (hypoxia),which is the result of inadequate oxygen supply,is closely connected with various diseases and occurs in tumor is a distinguished feature of malignant solid tumors,and the exploration of sensors which can accurately diagnose the oxygen level will be beneficial to estimate the malignant degree of tumor and subsequently execute more effective personalized imaging of metal plexes have attracted a great deal of attention because of their various
advantages,which include high Stokes shifts,color-tunable luminescence,pronounced photostability,long emission the ground state of 02 is a triplet state,the emission of triplet excked state of the transition plexes can he quenched by collision with 02,enabling the plexes to monitor the oxygen ,
majority of plex luminescence probes monitor the oxygen content with the intensity
variation at one wavelength,which can he affected by the concentration of probes,exciting
light intensity,and instrument e these problems,two plexes were synthesized with dual emission,and ratiometric monitored the oxygen
variation in living systems.
