The construction of an unprecedented intertwined spiral solvent channel is driven by weak C–Cl···O and C–H···N interactions based on extraordinary parallel spirals which were structured from supramolecular synthon macrocycle 1(C_(44)H_(44)N_4O_4) with a propargylamine backbone. The product is characterized by ~1H NMR, ~(13)C NMR, IR and HRMS, and further confirmed by single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group C2/c, with a = 28.922(3), b = 8.5069(9), c = 21.687(2) ?, β = 130.6320(10)o, V = 4049.4(7) ?~3 and Z = 8. A total of 11874 reflections were collected, of which 4942 were independent(Rint = 0.0590) and 2937 were observed with I > 2σ(I). The final full-matrix least-squares refinement gave R(I > 2s(I)) = 0.069 and w R = 0.167, S = 1.05,(Δρ)_(max) = 0.20 and(Δρ)_(min) =-0.22 e·?~(-3). The fluorescence of the product is discussed.
