The solution was heated at 120 degrees C while stirring for 30 minutes. Crystals were obtained from a solution containing the resulting solid dissolved in water. The crystals were recrystallized using methylcersolve so as to obtain a compound (A-8) with a production yield of 66 %. A photoelectric transducing device manufactured using this compound, exhibited a current density of 7.0 mA/cm2 at 0.62 V and it had a transducing coefficient of 2.86 %.
