S. Wenger et al., NEW PREORGANIZED CALIX[4]ARENES .2. DOUBLE SCHIFF-BASED CALIX[4]ARENES DERIVED FROM -DODECAMETHYL-5,11,17,23-TETRAHYDROXYCALIX[4]ARENE, Journal of inclusion phenomena and molecular recognition in chemistry, 20(2), 1994, pp. 151-156
We describe the condensation of an appropriate tetraaldehyde derivativ
e of mesitol calix[4]arene with 1,n-diaminoalkanes to afford double Sc
hiff-base calix[4]arene receptors in the 1,3-alternate conformation.
