Molecular parameters, viz. absorption [a0~(1) ]/emission [a~(1)] cross-sections, threshold intensity (Ip~h)/threshold pump rate (Wp,h), and fluorescence lifetime (r)/excited to ground state rate constant (As, ~s.) have been estimated in the case of 7 4 ethylamino trifluoromethyl coumarin (C-500) dy
## Abstract magnified image Several derivatives of coumarinโ3__N__โcarboxamides (**3โ21**) have been prepared via the reaction of the coumarinโ3โcarbonyl chloride (**1**) with a number of nucleophiles. Novel doubleโheaded coumarinโ3__N__โcarboxamides (**26โ33**) were also produced using the same m
The review focuses on the photochemical (singlet oxygen and photobleaching quantum yields) and photophysical (triplet quantum yields and lifetimes and fluorescence lifetimes) properties of metallophthalocyanine complexes containing main group metals (Zn, Al, Ge, Si, Sn, Ga and In) and some unmetalla
