摘要：In the solid state, amino acids (alanine and phenylglycine) with appended pyrene segments self-assembled into ahelix-like structures by asymmetrical H-bonds between carboxylic acid and amide segments, further inducing supramolecular tilted chirality of the achiral pyrenes. These structures bind melamine and electron-deficient units through Hbond and charge-transfer interactions, respectively. Chargetransfer interactions enhance the dissymmetry g-factor of
