Abstract:The self-assembly and chiral recognition are significant for ious fields. In this report, we studied the selfassembly of bisbenzocoumarins (DB) and their recognition with three kinds of small chiral molecules by spectroscopical and morphological methods. The results showed that low in solvent polarity could facilitate the aggregation of DB. Moreover, the chiral recognition of DB to 1-Phenylethanol (PE) occurred, which was confirmed by the circular dichroism (CD) spectra. The method of simulation chemistry was used to assist in understanding the recognition mechanism. It is supposed that the increased DB dihedral angle was caused by the non-covalent interaction between DB and PE. This work highlights the fundamental understanding of selfassembly of chiral bisbenzocoumarins and the chiral recognition to small molecules thereof.
