Hydrogels behave as potential candidates to investigate circularly polarized light (CP)-matter interaction, which however suffer from small sensitivity towards circular polarization. Here we report a general protocol build hydrogels π-conjugated amino acids with coassembled charge-transfer (CT) complexes, covering wide scope of donors and acceptors, were incorporated into stable hydrogel matrices. CT complexes formed block coassemblies gelators, induced the emergence macroscopic chiral helices, where efficient chirality transfer occurs realize tunable Cotton effects visible NIR-I region depending on structures pairs. The hybrid showed photothermal performances excellent heating-cooling cycling durability. Circularly NIR selectively triggered gel-solution phase transition at different timescales. Left- right-CP illumination generates up 2.5 folds difference in gel collapse time that allows for direct discrimination by naked eyes.
