资源简介：
Both
bulk crystals and nanocrystals of two helical complexes, [Cu(μ2-L)(H2O)]n (1) and {[Cu(μ2-L)(H2O)]·2H2O}n (2) (H2L
= thiazolidine-2,4-dicarboxylic acid), have been synthesized with
the chiralities of right-handedness (1) and left-handedness
(2), respectively. 4-Cyanopyridine and poly(vinylpyrrolidone)
(PVP) have been applied to control the synthesis of complexes with
different helicities in bulk-crystal and nanocrystal forms, respectively. 2 can be irreversibly transformed to 1 under
heating. Associated with the conformation changing, the symmetry alters
between nonpolar and polar space groups.
