الإجراء التجريبي
A 50 mg portion of Purpurin NT2 was dissolved in 20 ml dichloromethane, and the resulting solution was allowed to stand for a total of 16 hours in sunlight, in contact with air, and under ambient conditions (temperature about 22°). The dichloromethane was then removed by evaporation, leaving 50 mg porphyrin derivative (hereafter "Porphyrin NT2") which was found by nuclear magnetic resonance to have the formula of FIG. 7 of the attached drawings where R1 through R8 are ethyl, R10 through R12 are hydrogen, and R13 is CH2CH3. The production of Purpurin NT2 is described in Example 1 of PCT/US86/02824; it has the formula of FIG. 5 of the drawings of that application where R1 through R8 are ethyl, R9 is CO2CH2CH3, and R10 through R13 are hydrogen.
