| dc.abstract.en | Aluminium trimellitate [Al(OH)(BDC–COOH)] $\cdot0.9H_{2}O$ (1), the Al-MIL-53–COOH derivative, was discovered under solvothermal conditions using a high-throughput set-up suitable for microwave (MW)-assisted heating. The compound shows high structural flexibility. The large-pore (lp) form of the framework is obtained under large excess of $H_{2}O$ or after solvothermal treatment with N,N-dimethylformamide upon which [Al(OH)(BDC–COOH)] $\cdot$0.7DMF (2) is obtained. Exposure of the water rich lp form of 1 to ambient conditions leads to the transformation to the narrow-pore (np) form. Thermal activation of both compounds results in the formation of the empty lp form and the activation of 1 was studied in detail by in situ IR-spectroscopy. Depending on the activation temperature and time two post-synthetic modification (PSM) processes are observed: the partial decarboxylation and the formation of acid anhydride groups. Thus at high temperatures and long activation times [Al(OH)(BDC–OCOCO–BDC)$_{x/2}$ (BDC)$_{y}$](x+y= 1) is formed. Upon cooling in air the anhydride functionality still remains intact, but the np form is obtained in air due to the adsorption of $H_{2}O$ molecules. Sorption measurements of 1 confirm a preference for polar gases like $H_{2}O$ and $CO_{2}$ in comparison to $N_{2}$, $H_{2}$, and $CH_{4}$. The $N_{2}$ capacity depends strongly on the degree of decarboxylation. | pl |

Aluminium trimellitate [Al(OH)(BDC–COOH)] $\cdot0.9H_{2}O$ (1), the Al-MIL-53–COOH derivative, was
discovered under solvothermal conditions using a high-throughput set-up suitable for microwave
(MW)-assisted heating. The compound shows high structural flexibility. The large-pore (lp) form of
the framework is obtained under large excess of $H_{2}O$ or after solvothermal treatment with
N,N-dimethylformamide upon which [Al(OH)(BDC–COOH)]
$\cdot$0.7DMF (2) is obtained. Exposure of
the water rich lp form of
1
to ambient conditions leads to the transformation to the narrow-pore (np)
form. Thermal activation of both compounds results in the formation of the empty lp form and the
activation of
1
was studied in detail by
in situ
IR-spectroscopy. Depending on the activation
temperature and time two post-synthetic modification (PSM) processes are observed: the partial
decarboxylation and the formation of acid anhydride groups. Thus at high temperatures and long
activation times [Al(OH)(BDC–OCOCO–BDC)$_{x/2}$
(BDC)$_{y}$](x+y= 1) is formed. Upon cooling in air
the anhydride functionality still remains intact, but the np form is obtained in air due to the
adsorption of $H_{2}O$ molecules. Sorption measurements of
1
confirm a preference for polar gases like $H_{2}O$ and $CO_{2}$
in comparison to $N_{2}$, $H_{2}$, and $CH_{4}$. The $N_{2}$ capacity depends strongly on the degree of
decarboxylation. dc.affiliationpl
