Title: | Temperature Dependence of Excited Singlet S-1-State Deactivation in Corrole Free Bases | Authors: | Ajeeb, Y. H. Karlovich, T. B. Gladkov, L. L. MAES, Wouter Kruk, M. M. |
Issue Date: | 2019 | Publisher: | SPRINGER | Source: | JOURNAL OF APPLIED SPECTROSCOPY, 86(3), p. 389-395 | Abstract: | NH-tautomerization in the lowest excited singlet S-1-state of 5,10-mesityl-15-(2,6-dichloropyrimidinyl)corrole free base was studied in solution at 278-318 K and shown to be the dominant deactivation channel for electronic excitation energy of its short-wavelength tautomer T2. NH-tautomerization was found to cause significant changes in the deactivation quantum yields of electronic excitation energy of this tautomer as a function of temperature. About 90% of the electronic excitation energy of corrole molecules accumulated in the singlet S-1-state of long-wavelength tautomer T1 after phototautomerization if the temperature was increased to 318 K. | Notes: | [Ajeeb, Y.
