THE OCTAETHYLPORPHYRIN-DIHEXYLBITHIOPHENE DERIVATIVES COMBINED WITH PYRIDINE AND PYRIMIDINE RINGS. THEIR SYNTHESES AND PROTON-MEDIATED AND HEAT-DRIVEN SPECTRAL CHANGES

摘要

The octaethylporphyrin (OEP)-dihexylbithiophene (DHBTh) derivatives combined with pyridine (Pyr) and pyrimidine (Pym) as proton-acceptable rings (PAR) were synthesized, describable as OEP-DHBTh-PAR, in which all the OEP, DHBTh, and PAR components are connected with diacetylene linkage. Their ~1H NMR and electronic spectral properties and electrochemical behaviors were studied under the neutral and acidic conditions. Reversible proton-mediated and heat-driven spectral changes of OEP- DHBTh-PAR were performed, reflecting both properties of PAR and DHBTh.
