Fluorescence and X-ray crystallographic results for ammonium adducts of an anthraquinone-containing polyether macrocycle, 1,8-oxybis(ethyleneoxyethyleneoxy)-anthracene-9,10-dione (1), and an open-chain fluorinated analogue are presented. The crystal structure of a pseudo-polymorph of a hydrate of compound 1 is also presented. [1 2·NH4]PF6·MeOH (2), triclinic, P-1, a=10.5948(13), b=14.903(2), c=15.918(2), α=71.260(3), β=82.063(2), γ=69.258(2), Z=2, 5250 reflections [I≥2σ(I)], R1=0.0487, wR2=0.1190, 173(2) K; 1 4 ·H2O, Triclinic, P-1, a=12.0084(8) b=13.8050(9) c=23.8027(16), α=106.068(1), β=98.281(1), γ=90.047(1), Z=8, 8402 reflections [I≥2σ(I)], R1=0.0488, wR2=0.1086, 100(2) K. Different anti and gauche ring conformations are observed for macrocycles with and without guests complexed within the polyether ring.
