Abstract
Under the direction of dicationic bolaamphiphiles as SDAs (structure-directing agents), five new cuprous/silver halides(pseudohalides) formulated as {[BMIE][Ag2Br4]}n (1), {[BMIE][Ag2I4]}n (2), {[BMIB][Ag2Br4]}n (3), {(BDMIH)[Cu4(SCN)6]}n (4) and {[BDMIO][Cu2(SCN)4]}n (5) [BMIE·2Br=1,2-bis(3-methylimidozole-1-yl) ethane dibromide, BMIB·2Br=1,4-bis(3-methylimidozole-1-yl) butane dibromide, BDMIH·2Br=1,6-bis(2,3-dimethylimidozole-1-yl)hexane dibromide, BDMIO·2Br=1,8-bis(2,3-dimethylimidozole-1-yl)octane dibromide] were synthesized by self-assembly strategy in DMF–MeOH system. The X-ray crystallography analysis showed that these compounds were all composed of discrete organic cations and halocluster anions interacted by electrostatic interactions and hydrogen bonds. Compound 1 exhibits two-dimensional polypseudorotaxane structure. Compounds 2–4 present one-dimensional chain structure, compound 5 has a one-dimensional ladder-like structure. These compounds were characterized by IR, UV–Vis, PXRD and TGA. Their luminescent properties were further investigated in the solid state.
