Photoresponsive Crown Ethers. 13. Synthesis of Photoresponsive NS2O Crown Ethers and Application of the Cu(I) Complexes to O2-Binding
Photoresponsive crown ethers with heavy metal affinity were synthesized: They are the NS2O crowns bound to photofunctional azobenzene at 4,4'-positions via X(CH2 or CO) (1(X=CH2) and 1(X CO), respectively).They efficiently
