The structures of the molecular automata T-1 and T-2 and the Jablonski diagram depicting processes involved. a L indicates solvent molecules as ligands, water, or acetonitrile. Bodipy and the terpyridyl planes are orthogonal to each other due to the presence of 1,7-dimethyl substitution of the Bodipy chromophore. Double mTEG (methoxytriethyleneglycol) substitution at the boron center enhances water solubility. b Thicker green arrow is absorption, the other green arrows indicate radiative relaxations. Black-dashed arrows are non-radiative relaxation processes. Blue arrows indicate transitions between various excited states. CTS to T1 transition is particularly enhanced because of the orthogonal geometry of the terpyridyl-Bodipy diad. Energy levels were experimentally estimated using the spectral data (S1, CTS) in analogy to previous literature22, or based on the phosphorescence data32 for similar Bodipy compounds (T1)
