Fig. 6. (A) The kinetics of Ti14(NH4)2 and Ti14Cs2 catalyzed or photocatalyzed model reactions (Scheme 1) at room temperature. (B) The formation rate of 1b in the early stage of the cycloaddition reactions (see Fig. S10† for the calculations). (C) The reaction kinetics at 50 and 80 °C photocatalyzed by Ti14Cs2 under visible-light irradiation. (D) Arrhenius plots of the dark and the light reactions. The unspecified conditions are shown in Scheme 1.
