- •
Encapsulation of two donor–acceptor dyes with restrictive and unrestrictive C–N bond rotation by 尾-CD.
- •
Dye with hindered C–N bond rotation (N2) forms 1:1 complex at lower 尾-CD concentration.
- •
N2 forms 1:2 complex at a higher 尾-CD concentration.
- •
Dye with rotable C–N bond (DN2) undergoes only 1:1 complexation with 尾-CD.
- •
Quantum chemical calculations (PM3) confirm observed modes of encapsulation.
