text: Long-chain n-alkylamine surfactants have been used as structure-directing
agents in the synthesis of mesoporous aluminophosphates by a highly cooperative
formation mechanism in an alcoholic system. Small amounts of water in the synthesis
mixture play a significant role in the hydrolysis of the aluminum precursor (Al[OiPr]3)
and are important for the quality of the mesostructured products. The materials
exhibit disordered mesostructures, the stability and structural order of which
can be improved by a postsynthetic thermal treatment. The products are then stable
enough for the removal of the surfactant molecules by acidic solvent extraction,
yielding surface areas up to 690 m2/g.

text: Over the past few years a growing number of scientists have dedicated their
attention to the synthesis of mesostructured aluminophosphates following the concept
of supramolecular structure direction. Their research has produced a large variety
of synthetic approaches and yielded materials with various structural properties.
Today a substantial number of publications have accumulated; this short review
provides a general summary of the literature with the aim to display the opportunities
for future work.

text: Mesostructured aluminophosphate/dodecyl phosphate composite materials were
synthesized under aqueous and alcoholic conditions. The syntheses were monitored
by temperature- and time-resolved in-situ small-angle X-ray scattering (SAXS).
In the aqueous synthesis, a lamellar mesostructure is formed within the first
few minutes of the reaction; this structure maintains a constant d spacing independent
of the reaction time and temperature. The alcoholic synthesis at low temperature
yields a mixture of a lamellar and a supposedly inverted hexagonal mesostructure.
SAXS investigations show that these two phases evolve competitively. The lamellar
structure is favored by higher temperatures and/or longer synthesis times; above
∼70 °C it is formed exclusively. Mixtures of both phases can be isolated as solid
materials, but thermal analysis shows that the inverted hexagonal product transforms
into the lamellar phase at ∼35−43 °C. The alcoholic synthesis is a highly cooperative
reaction; the pure surfactant/alcohol systems are not lyotropic as long as the
inorganic reactants are absent. In comparison, the surfactant/water system with
the same surfactant concentrations as employed for the aqueous syntheses is lyotropic
with a lamellar structure.

text: The atomic structure of ordered mesostructured aluminophosphates with dodecyl
phosphate as the structure-directing template was investigated by multinuclear
solid-state NMR. Two different types of materials were studied: one with the
template headgroup as the only phosphate source and one where additionally phosphoric
acid was used in the synthesis. All 31P and 27Al NMR resonances can be subdivided
into three groups depending on the sample composition. Furthermore, 2D heteronuclear
correlation NMR measurements allow a conclusive and unambiguous identification
of the phosphate headgroup resonances of the template molecules and the determination
of water and/or hydroxyl units. Most notably, there is an obvious correlation
between the d001 values of the samples as measured by powder X-ray diffraction
and the appearance of the various groups of 27Al and 31P resonances.

text: Mesostructured aluminophosphate / surfactant composite materials were prepared
from aqueous and alcoholic systems. Syntheses in ethanol or methanol, respectively,
lead to mixtures of two nanostructured phases. One of these consists of hexagonally
arranged rod-like assemblies of the surfactant molecules with the head groups
located in the centres, encapsulating the inorganic aluminophosphate; the other
is lamellar. The syntheses were monitored by in-situ temperature- and time-resolved
small angle X-ray scattering (SAXS).

text: We report on the synthesis of lamellar mesostructured aluminophosphate composites
which contain variable relative amounts of aluminium oxide species in the core
regions of the lamellae; this is investigated quantitatively by Al K-edge XANES
spectroscopy. Templating is achieved by the utilisation of monododecyl phosphate
surfactant. If no phosphorous source (such as H3PO4) is used for the synthesis,
the phosphate head groups of the surfactant become incorporated into the inorganic
network to form similar lamellar aluminophosphate structures. Thus, the surfactant
serves as both template and reactant.

text: Lamellar mesostructured aluminophosphates were synthesized from aluminum triisopropoxide
and phosphoric acid; monododecyl phosphate surfactant was used as structure-directing
template. Depending on the relative Al/P ratio in the samples, variable relative
amounts of tetrahedrally and octahedrally coordinated Al are found, indicating
that both aluminophosphate and aluminum oxide species (as thermodynamically favored)
are being formed in the syntheses. This is investigated quantitatively by Al K-edge
XANES spectroscopy. The same syntheses were carried out without phosphoric acid,
resulting in similar lamellar structures. The inorganic lamellae of these products
consist to a significant extent of aluminophosphate rather than exclusively of
aluminum oxide, which means that the phosphate headgroups of the surfactant molecules
become incorporated into the inorganic network. Thus, for the first time, the
surfactant serves as both template and reactant.
