9,10-Diphenylanthracene |
|
| The chemical structure of 9,10-Diphenylanthracene is shown at the right. The absorption and fluorescence emission spectra are shown below. The structure, absorption, and fluorescence data were all obtained from the PhotochemCAD package by Jonathan Lindsey. This excellent program allows rapid comparison of spectra and enables one to do a variety of photochemically relevant calculations. |

Absorption
This is a graph of the molar extinction coefficient of 9,10-Diphenylanthracene dissolved in cyclohexane. It was measured by R. A. Fuh on 6/26/95 [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. 9,10-Diphenylanthracene has a molar extinction coefficient of 14,000 M-1cm-1 at 372.5 nm [I. B. Berlman, Handbook of Fluorescence Spectra of Aromatic Molecules, Academic Press, 1971]. Other fluorescence yields include 0.90 in cyclohexane [S. Hamai and F. Hirayama, "Actinometric determination of absolute fluorescence quantum yields.," J. Phys. Chem., 87, 83-89, 1983] [S. R. Meech and D. Phillips, "Photophysics of some common fluorescence standards.," J. Photochem., 23, 193-217, 1983] [D. F. Eaton, "Reference materials for fluorescence measurement," Pure Appl. Chem., 60, 1107-1114, 1988]. |

Fluorescence
This is the fluorescence emission spectrum of 9,10-Diphenylanthracene dissolved in cyclohexane. The spectrum was taken by R. A. Fuh on 6/26/95 using an excitation wavelength of 350 nm [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. The quantum yield is 1.0 [I. B. Berlman, Academic Press, 1965]. |
