Emission from charge recombination during the pulse radiolysis of arylethynylpyrenes

Article Abstract:

Emission from several 1-(arylethynyl)pyrenes with a substituent on the aryl group (REPy, R = phenyl (PEPy), 4-dimethylaminophenyl (NPEPy), 4-isopropoxyphenyl (OPEPy), 2-quinonyl (QEPy), and 9-(10-cyanoanthracenyl) (AEPy)) is analyzed with time-resolved fluorescence measurements during pulse radiolysis in benzene. The results have emphasized that all REPy's show emission during pulse radiolysis in benzene, while only two compounds (NPEPy and OPEPy) emit electrogenerated chemiluminescence (ECL).

Rapid exciton migration and fluorescent energy transfer in helical polyisocyanides with regularly arranged porphyrin pendants

Article Abstract:

Photophysical properties of polyisocyanides possessing porphyrin pendants are investigated by steady state and transient spectroscopic methods. The resulting substantial exciton coupling in the porphyrin polymers is also examined.
