a An illustrated diagram of the biological HR channel with Schiff base group serving as the selective filter and photo-receptor. b Schematic of bioinspired light-driven chloride pump with porphyrin acting as the photo-receptor and selective ion transport site. The defects in the helical channel are repaired by the doping of TPP. c TEM image of p-BCP@4TPP, exhibiting periodic nanocylinder structure (Scale bar: 500 nm). Inset: an enlarged TEM image (Scale bar: 100 nm). d 2D GI-SAXS patterns of p-BCP@nTPP membranes, indicating vertically aligned nanocylinder structure. e 1D intensity profiles of corresponding 2D WAXD patterns, indicating porphyrin doping-repaired aggregates. f CD spectra of p-BCP@nTPP membranes. The positive signals at 417 nm indicate the helical porphyrin channel structure for membranes.
