All the teabags were put into a resin kettle under nitrogen. Fifteen equivalents of boric acid and 15 equiv. of trimethylborate were added followed by the slow addition of 45 equiv. of borane (1 M in THF). After hydrogen production ceased, the reaction was heated at 65° for 72 h. The reaction solution was decanted and quenched by the slow addition of methanol. The resin was washed with methanol, THF, and piperidine. The polyamine-borane complex was disproportionated by overnight treatment (16 h) with piperidine at 65° followed by washes with DMF, DCM, and methanol. 

Thus, the data on photochemical hydrogen production indicate that macrobicyclic complexes can be effective ETAs only in a narrow redox potential range (-400 mVexperiments demonstrated that cage complexes with such potentials are efficient for quenching of [Ru(bpy)3]2+ and [Ru(4,4 -Me2bpy)3] + cations (Table 63).
