hydroxycinnamoyl glucose esters during preparation were investigated to prevent these in subsequent synthetic attempts. Photoisomerization gave an isomeric mixture containing the trans-esters and undesired cis-esters, and acyl migration resulted in a mixture of the desired 1-O-β-ester and two additional migrated forms, the 2-O-α- and 6-O-α-esters. Theoretical studies indicated that the photoisomerization was facilitated

Molecular recognition directed supramolecular control over perylene-bisimide aggregation resulting in aggregation induced enhanced emission (AIEE) and induced chiral amplification
Recognition directed spontaneous assembly formation has been used to build-up a sensory system with perylene bis-guanidinium (PBG), which presented great response towards chiral guest sensing. Based on structural modification in the chiral guest molecules, PBG can selectively recognize dibenzoyl tartaric acid (DBTA) among the other tartaric acids (TA), resulting in an explicit read-out of molecular
