Three novel cation-templated complexes, (BPE)3[Ag4Br4(SCN)6]}n (1), (DEBP) [Cu2(SCN)4]}n (2) and (DIBP) [Cu2(SCN)4]}n (3) [BPE = 1, 2-bis (pyridinium) ethane; DEBP = 1, 1′-diethyl-4, 4′-bipyridinium dibromide; DIBP = 1, 1′-diisopentyl-4, 4′-bipyridinium], have been synthesized viaself-assembly reaction in solution. Complex 1 possesses a one-dimensional polyrotaxane architecture with the organic cation BPE trapped in it, whereas both compounds 2 and 3 are infinite 2D supramolecular polypseudorotaxane, linked by bridging thiocyanate groups. All compounds were further characterized with IR spectra, thermal analysis, ultraviolet and fluorescence properties.
