我们合成了一种新型的绿光响应型四邻异丙氧基取代偶氮苯（ipAzo）。顺式ipAzo与γ-环糊精（γ-CD）形成强的主客体复合物，而反式ipAzo结合较弱。这种新的光响应性主客体相互作用与众所周知的偶氮苯（Azo）/α-环糊精（α-CD）复合物相反，后者仅在trans-Azo和α-CD之间强。将紫外光响应的Azo/α-CD和绿光响应的ipAzo/γ-CD主客体复合物相结合，构建了光响应的正交超分子体系。
We synthesized a novel green-light-responsive tetra-ortho-isopropoxy-substituted azobenzene (ipAzo). Cis-ipAzo forms a strong host-guest complex with γ-cyclo dextrin (γ-CD) whereas trans-ipAzo binds weakly. This new photoresponsive host-guest interaction is reverse to the well-known azobenzene (Azo)/α-cyclodextrin (α-CD) complex, which is strong only between trans-Azo and α-CD. By combining the UV-light-responsive Azo/α-CD and green-light-responsive ipAzo/γ-CD host-guest complexes, a photoresponsive orthogonal supramolecular system is developed.
