Three 4'-(dansylamino)benzo crown ethers I (n = 1, 2, 3) have been synthesized from B12C4, B15C5, and B18C6 via nitration, catalytic hydrogenation and dansylation successively. The other one, 4'-[a-(dansylamino)ethyl]benzo-15-crown-5, has also been synthesized but from B15C5 via acetylation, Leuckart reaction and dansylation. These dansylamino derivatives are new species of fluorescent crown ethers.
