Application

4,7-Diphenyl-1,10-phenanthroline, 98.5%, is a versatile and highly effective compound that serves various applications due to its unique properties. As a bidentate ligand, it is extensively used in the determination of iron, particularly in serum and urine, through colorimetric methods. Its utility extends to acting as a scavenger reagent, effectively removing traces of iron and copper from reagent solutions, which is crucial in trace metal determinations. Additionally, it plays a significant role in enhancing the efficiency of organic photovoltaic cells by acting as a hole-blocking or exciton-blocking layer with its wide energy gap and high ionisation potential. Further applications involve its use in catalysis and in the copper-catalyzed protodecarboxylation of aromatic carboxylic acids. Moreover, the iron complex of this compound functions as a redox mediating agent for imaging surface-immobilized DNA using Scanning Electrochemical Microscopy (SECM), and it is employed in ultra-sensitive and selective non-extractive quenchofluorimetric methods for determining palladium (II) at microgram per liter levels. Overall, 4,7-Diphenyl-1,10-phenanthroline is a critical component in improving analytical techniques and enhancing the performance of photovoltaic devices.
