• present amphiphile is originated from bent aromatic amphiphile AA [12][13], composed of two anthracene panels linked by a m-phenylene spacer with two cationic side-chains, which assembles into an aqueous ≈2 nm-sized aromatic micelle with broad host functions [14][15][16][17][18][19][20][21].

• and structure of aromatic micelles Aromatic micelle (PA-CH3)n was facilely generated via dissolution of PA-CH3 (2.1 mg, 4.3 μmol) in water (8.6 mL). The 1H NMR spectrum of PA-CH3 in D2O showed significantly upfield-shifted signals (Δδ = −2.73 ppm for Hb) compared to the spectrum in CD3OD, in a manner
