metathesis (RCM) reactions of suitable substrates having terminal olefins, which are assembled from various linkers and hydroxy benzaldehydes and syntheses of a wide range of 16–30 membered, new crown ether-type polyether, aza-polyether, bis aza-polyether macrocycles and dilactone moiety embedded polyethermacrocycles (macrolides) are reported. After the ring-closure reaction, installation of different functional

skeletally interesting, 18–27 membered, polyethermacrocycles having a 1,3-diyne unit-based cylindrical backbone are reported. The utility of polyethermacrocycles having the 1,3-diyne units is shown by incorporating isoxazole and thiophene moieties into the macrocycles. The structures of representative crown ether/polyether-type macrocycles were unambiguously established from single crystal X-ray structure

sulfur-to-sulfur separations (S-(CH2)n-S, L1: n = 2, L2: n = 3) and copper(ii) nitrate afforded new types of both monocopper(ii) and dicopper(ii) complexes, respectively. L1 gave a 1D coordination polymer [Cu2(L1)2(NO3)4]n (1) based on a convergent exo-coordination mode while L2 resulted in the formation of a divergent exo/exo-coordinated dicopper(ii) complex, [Cu2(L2ox)4(μ-Cl)](NO3)4 (2), whose shape resembles
