Mg-phthalocyanine |
|
| The chemical structure of Magnesium phthalocyanine (MgPc), PrOH 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 Magnesium phthalocyanine (MgPc) dissolved in PrOH. It was measured by R. A. Fuh on 6/28/95 [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]. Magnesium phthalocyanine (MgPc), PrOH has a molar extinction coefficient of 87,100 M-1cm-1 at 668.25 nm [M. Whalley, "Conjugated macrocycles. Part XXXII. Absorption spectra of tetrazaporphyrins and phthalocyanines. Formation of pyridine salts.," J. Chem. Soc., 866-869, 1961].

Fluorescence
This is the fluorescence emission spectrum of Magnesium phthalocyanine (MgPc) dissolved in PrOH. The spectrum was taken by R. A. Fuh on 6/28/95 using an excitation wavelength of 600 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 0.76 [A. T. Gradyushko, A. N. Sevchenko, K. N. Solovyov, and M. P. Tsvirko, "Energetics of photophysical processes in chlorophyll-like molecules," Photochem. Photobiol., 11, 387-400, 1970]. |
