Radiationless deactivation and anomalous fluorescence of singlet 1,12 benzperylene ( Book )
1 edition published in 1968 in English and held by 1 WorldCat member library worldwide
Values of the rate constants for processes that deactivate the lowest excited singlet state of 1,12 benzperylene were determined between -196C and 23C from measurements of the quantum yields of triplet formation, fluorescence, and the fluorescence lifetime. The rate constant for intersystem crossing to the triplet state is nearly same at -196C and +23C. The rate constant for direct radiationless deactivation to the lowest singlet is probably zero at -196C but increases to 600000/sec at +23C. This is similar to results obtained for other aromatic hydrocarbons. However, the fluorescence of 1,12 benzperylene is atypical. An increase in the rate constant of fluorescence, k1, from -196C to +23C is observed resulting from an increase in fluorescence with temperature while fluorescence lifetime decreases over the same temperature range. The increase in k1 with increasing temperature is attributed to a temperature dependent emission from the second excited singlet state. Since the second excited singlet state of 1,12 benzperylene lies only 1275 to 1400/cm above the (1)Lb state, there is significant thermal population of the (1)La state of +23C. The observation of a temperature dependent anti stokes fluorescence supports this interpretation. The effect of solvent upon the energy gap between the (1)La and (1)Lb state and the fluorescence properties of 1,12 benzperylene is discussed. (Author)

Fluorescence and phosphorescence of aromatic hydrocarbons in poly(methylmethacrylate) as a function of temperature ( Book )
1 edition published in 1968 in English and held by 1 WorldCat member library worldwide
Fluorescence lifetimes (t) and fluorescence yields(P) of poly(methylmethacrylate) samples containing coronene-h12, coronene-d12, pyrene-h10, pyrene-d10, 1,2;5,6 dibenzanthracene, 1,2;7,8 dibenzanthracene, 1,2;3,4 dibenzanthracene, 1,2 benzcoronene and 1,12 benzperylene were measured. For all compounds studied, except coronene-h12 and coronene-d12, t decreases with increasing temperature. For all compounds except 1,12 benzperylene and 1,2;3,4 dibenzanthracene, P decreases proportionally with t so that the radiative lifetime (t) is temperature independent. For the two last mentioned compounds t varies with temperature. This may be due to the closeness of the p band to the lowest-lying alpha band. The activation energies of temperature dependent quenching of t are all similar. The quenching is related to Lin's theory of radiationless transitions and it is suggested that this temperature dependent quenching is due to S1 -- So transitions. (Author)
