Application


  • A high molar extinction coefficient bisterpyridyl homoleptic Ru(II) complex with trans-2-methyl-2-butenoic acid functionality: potential dye for dye-sensitized solar cells.: This study explores the synthesis and application of a Ru(II) complex incorporating trans-2-methyl-2-butenoic acid as a dye for dye-sensitized solar cells. The high molar extinction coefficient and favorable photophysical properties make this compound a promising candidate for enhancing solar cell efficiency (Adeloye et al., 2012).

  • Synthesis, photophysical and electrochemical properties of a mixed bipyridyl-phenanthrolyl ligand Ru(II) heteroleptic complex having trans-2-methyl-2-butenoic acid functionalities.: This research focuses on the synthesis and characterization of a Ru(II) heteroleptic complex with trans-2-methyl-2-butenoic acid functionalities. The study highlights the compound′s photophysical and electrochemical properties, demonstrating its potential for use in optoelectronic devices and catalytic applications (Adeloye, 2011).
