We report herein synthetic results obtained new types of crown ethers containing coumarin group. Crown ethers containing coumarin group 1 ~ 3 are hydroxymethyl-15-crown-5-ether linked with 4-hydroxy coumarin-4-acetic acid by esterification reaction. Crown ethers containing coumarin group 1 ~ 3 have different cavity in each crown ether rings. The 12-crown-4 ether with coumarin 1 has the smallest cavity size. The 15-crown-5 ether with coumarine 2 has the medium cavity size. The 18-crown-6 ether with coumarin 3 has the largest cavity size. The synthesized crown ethers were characterized respectively by IR, NMR. GC-Mass.
