Reaction of Ti(OiPr)4 with several tri- and

tetracarboxylic acids, followed by hydrolysis, resulted in microporous,

structured materials, with microporous surface areas up to 340 m2 g−1. Depending on the kind of carboxylic acid, the Ti:COOH ratio and the Ti:H2O

ratio, either pillared layered or surface fractal 3D structures were

obtained according to SAXS measurements. The most pronounced layered

structure was found for 1,2,4,5-benzenetetrabenzoic acid and a Ti:H2O ratio of 4, while a Ti:H2O

ratio of 2 resulted in a 3D structure. The use of

1,3,5-benzenetricarboxylic acid or 1,3,5-benzenetribenzoic acid resulted

in similar structures which, however, were less pronounced and less

ordered. The reaction of tetrakis(4-carboxyphenyl)silicon with Ti(OiPr)4 or benzenetribenzoic acid with Zr(OiPr)4 gave 3D structures for all Ti:H2O ratios.
