Abstract

A highly methanol-selective vapochromic response has been realized in a NiII-quinonoid complex, [Ni(HLMe)2] (H2LMe=4-methylamino-6-methyliminio-3-oxocyclohexa-1,4-dien-1-olate) which exhibits a reversible structural transformation including a coordination geometrical change between the square-planar and octahedral structure by the selective uptake of methanol vapor. This was accompanied by a remarkable color change between purple and orange, as well as temperature-robust spin-state switching in the solid state under ambient conditions. It is remarkable that the properties are derived by the fine structural modification of the quinonoid ligand such as methyl or ethyl analogues. Such a system has high potential for applications in memory devices as well as chemical sensors and smart responsive materials. [ABSTRACT FROM AUTHOR]

9. Stereoselektive thermische Umwandlung von s-trans-Diallenen über s-cis-Diallene in Dimethylencyclobutene im kristallinen Zustand

Abstract

Eine konrotatorische [2+2]-Cyclisierung ist der zweite Schritt der thermischen, im Festkörper stattfindenden Umwandlung der s-trans-Tetraaryldibromhexatetraene 1 in die Cyclobutene 4. Vor der Cyclisierung lagert sich 1 in das s-cis-Konformer 3 um. Überraschend ist, daß die thermische Umwandlung und die stereoselektive Cyclisierung trotz der erforderlichen Bewegungen der sterisch anspruchsvollen Substituenten so leicht möglich sind. R = Ph, p-MeC6H4.
