| The chemical structure of N,N'-Difluoroboryl-1,9-dimethyl-5-phenydipyrrin 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 N,N'-Difluoroboryl-1,9-dimethyl-5-phenydipyrrin dissolved in toluene. It was measured by Richard W. Wagner on 94 [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]. N,N'-Difluoroboryl-1,9-dimethyl-5-phenydipyrrin has a molar extinction coefficient of 54,000 M-1cm-1 at 503 nm [R. W. Wagner and J. S. Lindsey, "Boron-dipyrromethene dyes for incorporation in synthetic multi-pigment light-harvesting arrays.," Pure Appl. Chem., 68, 1373-1380, 1996].

Fluorescence
This is the fluorescence emission spectrum of N,N'-Difluoroboryl-1,9-dimethyl-5-phenydipyrrin dissolved in toluene. The spectrum was taken by Richard W. Wagner on 94 using an excitation wavelength of 485 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 0.053 [R. W. Wagner and J. S. Lindsey, "Boron-dipyrromethene dyes for incorporation in synthetic multi-pigment light-harvesting arrays.," Pure Appl. Chem., 68, 1373-1380, 1996]. |
