The values of luminescence quantum yield and duration have been measured for rhodoporphyrin XV, deoxophyllerythrin, phyllerythrin, etiochlorin, chlorin e6 and their zinc complexes as well as for bacteriochlorin and isobacteriochlorin. The effect of the structural elements, which are characteristic of the chlorophyll molecule, on the probabilities (rate constants) of primary photophysical processes has been traced. It has been shwon, in particular, that all these elements enhance the radiationless de-excitation of the lowest triplet state. |
