one-dimensional channels and high density of open metal sites, the activated 1a was applied as a heterogeneous catalyst for the formation of C–C bonds of carbonyl compounds in the absence of solvents, which shows high efficiency and size-selectivity. Furthermore, the possible reaction mechanism has been proposed based on the experimental results. The treatment activity of the new compound on the Mg63 osteosarcoma

The invention concerns modified polyamides, and more particularly polyamides comprising units of the type obtained by reacting a diacid on a diamine, modified by a multifunctional compound. Finished articles formed from said polyamides or from compositions based on said polyamides exhibit excellent mechanical properties, as well as a very good surface appearance. The inventive modified polyamide is obtained by mixing in melted state polyamides of different types, in the presence of a multifunctional compound.
The present invention relates to the compounds of the formula (1) and to organic electronic devices in which these compounds are used as matrix material in the emitting layer and/or as hole-transport material and/or as electron-blocking or exciton-blocking material and/or as electron-transport material.

(Ln-MOF) Nd-cdip (H4cdip = 5,5′-carbonyldiisophthalic acid) was successfully synthesized, which could be used as an efficient heterogeneous catalyst for cyanosilylation and the synthesis of 2,3-dihydroquinazolin-4(1H)-onederivatives at room temperature based on the Lewis acid sites in the channels of the MOF. Moreover, Nd-cdip had an excellent turnover number (500) for catalyzing cyanosilylation in no
