A blue photoluminescent 2-D coordination polymer constructed by dinuclear zinc(II) subunits [Zn2(OZ)2] [Hoz=2-(2′-hydroxyphenyl)-2-oxazoline] and dicyanamide

Substitution of the terminal oz group of the dinuclear [Zn(oz)(2)](2) complex (1) with dicyanamide [where Hoz = 2-(2'-Hydroxyphenyl)-2-oxazoline] results in the formation of a 2-D coordination polymer [Zn(oz)N(CN)(2)](n) (2) based on [Zn-2(oz)(2)] subunits. Both compounds exhibit strong blue photoluminescence but the coordination polymer 2 has greater thermal stability than the dinuclear complex 1. (C) Wiley-VCH Verlag GmbH Co.
