| The chemical structure of N,N'-Difluoroboryl-1,9-dimethyl-5-(4-iodophenyl)-dipyrrin 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-(4-iodophenyl)-dipyrrin 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-(4-iodophenyl)-dipyrrin has a molar extinction coefficient of 59,000 M-1cm-1 at 515.5 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-(4-iodophenyl)-dipyrrin 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 0.23 [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]. |
