摘要: Because restricted molecular rotation is the main mechanism responsible for aggregation-induced emission (AIE), a Jeffamine-included polyrotaxane (JCD) was therefore used in this study as rigid template to impose effective rotational restriction on AIE-active luminogen of 1,2-bis(2,4-dihydroxybenzylidene)hydrazine (CN4OH). Besides rigidifying flexible Jeffamine chain, β-cyclodextrin (β-CD) rings JCD also provided hydroxyl (OH) groups hydrogen bond OHs CN4OH, furnishing emissive CN4OH/JCD(x/y) (x/y: molar ratio between CN4OH and JCD) blends with efficiency higher than pure itself. Dependent composition blends, CN4OHs are arrayed differently experience varied levels thus emit an intensity correlated arrangement blends. The relationship arrangement, AIE-oriented behavior focus study.
