Disclosed herein is a three-dimensional coordination complex that includes a plurality of inorganic centers; a plurality of a first bis(bidentate) linker; and a plurality of a second bis(bidentate) linker, where the first and the second bis(bidentate) linkers are have different lengths, and the bidentate binding sites on each linker face in opposite directions on an axis.
Liquid crystal polyester derived from phenylene-naphthalene monomers and one or more comonomers display an improved balance of properties, including low melt viscosity, fast cycle time in molding, very low mold shrinkage, high tensile and/or flexural strength, solvent resistance, excellent barrier properties, low water absorption, low thermal expansion coefficient, excellent thermostability, and/or low flammability. The phenylene-naphthalene monomers are
The one or more comonomers include 4-hydroxybenzoic acid, 2-hydroxy-6-naphthoic acid, terephthalic acid, isophthalic acid, and derivatives and combinations thereof.
