a Decrease process of transmittance at 650 nm of SMC-PEI under 420 nm irradiation from 0 s to 1170 s. Inset: Tyndall effect photos at different irradiation time. b Optical transmittance at 650 nm during thermal deformation process of SP-PEI over time. Inset: Tyndall effect photos after different time in the dark. c Transmittance spectra of SMC-SP-PEI, SP-PEI, SMC, SMC-PEI, PEI, SP solutions. d Transmittance at 650 nm of c and the corresponding cubic error bars. n = 3 independent experiments, with the bar data indicating mean ± SD. ([SMC]initial = 0.225 mM, [PEI] = 5 μg mL−1). e Partial 1H-NMR spectra (600 MHz, DMSO-d6) of SMC- PEI, SP-PEI, SMC-SP-PEI.
