A composition for film formation which comprises:
(A) a product of hydrolysis and condensation obtained by hydrolyzing and condensing at least one silane compound selected from the group consisting of compounds represented by the formula (1), compounds represented by the formula (2), and compounds represented by the formula (3) in the presence of water and an ammonium compound, and
(B) an organic solvent.

Tri-n-butylammonium trichloroacetate (TBAT), a novel hybrid material, undergoes a reversible phase transition around 196 K, which is triggered by torsion in the cations and the order–disorder transformations of both ions.

The rate constants, k, for the decomposition of ammoniumtrichloroacetate in acetonitrile were determined at 298 K BHCCl3COO [graphic omitted] CHCl3+ CO2+ B where B is an N-base. The first-order decarboxylation of trichloroacetic acid in the presence of N-bases is strongly dependent upon proton transfer in ([graphic omitted]) complexes.
三氯乙酸铵在乙腈中的分解速率常数k在298 K BHCCl 3 COO CHCl 3 + CO 2 + B处测定,其中B为N基。在N碱存在下三氯乙酸的一级脱羧作用在很大程度上取决于质子在(复合物)中的质子转移。
