  Bis(5-carbomethoxy-1,3-phenylene)-(3x + 2)-crown-x compounds [x = 6 (3a), x = 8 (3b), and x = 10 (3c)] have been synthesized in one step by reaction of methyl 3,5-dihydroxybenzoate oxybenzoate (1) and the corresponding oligo(ethylene glycol) dichlorides (2a, 2b, and 2c) in the presence of NaH or KH in N,N-dimethylformamide (DMF). The smaller monoester, 5-carbomethoxy-1,3-phenylene-16-crown-5 (4c), was also isolated along with 3c. The X-ray crystal structures of these macrocycles (3b, 3c, and 4c) have been determined. Macrocycle 3b crystallizes in the triclinic space group P-1 with unit cell parameters of a = 8.632(2) Angstrom, b = 10.006(2) Angstrom, c = 11.527(2) Angstrom, alpha = 78.30(3)degrees, beta = 71.98(3)degrees, gamma = 65.00(3)degrees. Macrocycle 3c crystallizes in the triclinic space group P-1 with unit cell parameters of a = 8.911(2) Angstrom, b = 9.497(2) Angstrom, c = 10.140(2) Angstrom, alpha = 93.66(2)degrees, beta = 94.03(1)degrees, gamma = 105.95(1)degrees. Macrocycle 4c crystallizes in the triclinic space group with unit cell parameters of a = 8.748(2) Angstrom, b = 9.163(2) Angstrom, c = 12.025(3) Angstrom, alpha = 74.90(2)degrees, beta = 86.81(2)degrees, gamma = 61.73(2)degrees. The thermal stabilities of these macrocycles and the complexation abilities of the bis(m-phenylene)-32-crown-10 derivatives with methyl viologen bis(hexafluorophosphate) (8) have been examined by H-1 NMR spectroscopy.

  Poly(ester crown ether)s were synthesized by direct condensation of bis(5-carboxy-m-phenylene)-(3x + 2)-crown-x, x = 6, 8 and 10 (1a, 1b and 1c) with bisphenols via the Higashi method. The formation of higher molecular weight poly(ester crown ether) 5 from the 32-membered crown ether 1c and bisphenol-A (2a) as compared to polyester 3 from 20-membered crown ether 1a and bisphenol-A, polyester 4 made from the 26-membered crown ether 1b and bisphenol-A (2a) and polyester 6 derived from 32-membered 1c and bis(p-t-butylphenyl)-bis(p-hydroxyphenyl)methane (2b) under identical conditions is believed to be the result of threading (rotaxane formation) in 5 but no or less threading in 3, 4 or 6; indeed polyester 3 provides a control because its macrocyclic component (1a) too small to be threaded, even by a polymethylene chain. Threading in 5 was undetectable through NOESY experiments. However, melt polymerization of bis(5-hydroxymethyl-m-phenylene)-32-crown-10 (7) with sebacoyl chloride (8) gave an insoluble, but swellable elastomeric material 9, a polyrotaxane network, as a result of more extensive in situ threading brought about by hydrogen bonding of the crown ether with the alcohol moieties in the more concentrated medium.
