Products of Photodegradation for Coumarin Laser Dyes. (1998)
Jones,G. , II, Jackson,W. R., Kanoktanaporn,S., Bergmark,W. R.
The products of conventional photolysis of the coumarin laser dyes, C1, C35, C153, and C152 have been investigated, The previously reported dealkylation of C1 is documented for the fluorinated dyes,...
Photodegradation of Coumarin Laser Dyes. An Unexpected Singlet Self-Quenching Mechanism. (1998)
Jones,G. , II, Bergmark,W. R.
Photolysis of aminocoumarine laser dyes, including 7-diethylamino-4-methyl-coumarin has been investigated. Dealkylation of groups at the 7-dialkylamino functionality, reduction of the lactone moiety...
Electron Donor-Acceptor Quenching and Photoinduced Electron Transfer for Coumarin Dyes. (1998)
Jones,G. , II, Griffin,S. F., Choi,C., Bergmark,W. R.
The fluorescence of 7-aminocoumarins is quenched by a variety of organic electron donors or acceptors in acetonitrile. In general, donors with half-wave oxidation potentials less positive than 1.0 V...
Jones,G. , II, Jackson,W. R., Choi,C., Bergmark,W. R.
Photophysical parameters have been determined for coumarin laser dyes in organic solvents and water. Fluorescence yields and lifetimes were sensitive to solvent polarity depending on subtle features...
Photophysical and Photochemical Properties of Coumarin Laser Dyes in Amphiphilic Media. (1998)
Jones,G. , II, Jackson,W. R., Kanoktanaporn,S., Bergmark,W. R.
Photophysical properties of coumarin laser dyes solubilized in aqueous detergent or cyclodextrin solutions have been investigated. Dyes appear to be incorporated in hydrated (hydrogen bonded) sites...
