a Schematic illustration of the biomimetic film. b Absorption profiles and illustrations of forward (trans-to-cis) and backward (cis-to-trans) photoisomerization of azobenzenes in the G-TXr-AZO-PdNc1 films via singlet absorption (λex = 340 or 365 nm, Io = 2.85 mW cm−2) and triplet sensitization (λex = 850 nm, Io = 107 mW cm−2), respectively.
