Abstract

A compound of Formula (II) and (III), or a mixture of any two or more thereof; wherein M is Ti or Zr; R³ at each occurrence is H, F, Cl, Br, I, CN, OR⁴, NR⁵R⁶, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylalkyl, unsubstituted heterocyclyl, or substituted or unsubstituted heterocyclylalkyl; R⁴ is H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylalkyl, unsubstituted heterocyclyl, or substituted or unsubstituted heterocyclylalkyl; R⁵ and R⁶ are independently H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocyclylalkyl, or R⁵ and R⁶ may join to form a heterocyclic ring containing the N to which they are attached; and n′=0-4. Such compounds form optically transparent and/or clear films or particles or may be used to prepare such materials.
