focuses synthesis of novel 4‐aminomethyl‐7,8‐dihydroxy coumarins and their crown ether derivatives. The purified novel coumarins and their crown ether derivatives were identified by 1H NMR, 13C NMR, mass spectrometry and elemental analysis. The 1:1 binding constants of Ca2+, Mg2+, Fe2+, Zn2+, Ni2+, Cd2+, Co2+, and Mn2+ ions at 25°C ± 0.1 with the 4‐aminomethyl‐7,8‐dihydroxy coumarins and their crown ether
