Synthesis, Structure And Properties Of Some Aryleneethynylene Ferrocene Derivatives

Recently, photoactive donor-conjugated link-acceptor dyads have attracted significant attention and deep research. A study on design, synthesis and functions of receptors with ferrocene as redox-active center was systematically carried out. The main results are as follows:1,The synthesis, optical and electrochemical properties of three ethynyl-bridged ferrocenes with electron donor groups are presented. Upon oxidation, L1 and L3 appear ligand to metal charge transition (LMCT) in near-IR range (946nm and 1044 nm, respectively).And L2 shows optical and electrochemical responses upon protonation.2,The synthesis, optical spectroscopic and electrochemical studies of two new ferrocenyl-acridine and five new ferrocenyl-quinoline dyads withπ-conjugated spacer are presented. Compared with the extended system,L6,L8,L10 and L12 offers stronger and lower-energy metal to ligand transfer (MLCT) transition, meanwhile,we studied the multiresponse to protons and selected metal ions.3,The synthesis, optical spectroscopic and electrochemical studies of three ferrocene-based thiourea receptors are presented. The structures for all these new compounds were fully characterized by IR and 1H NMR. In addition, these receptors show multiresponse to selected anions.
