Shape-Switchable Azo-Macrocycles

The synthesis of four shape-switchable macrocycles comprising different peripheral substituents is described. The macro- cycles 1-4 consist of m-terphenyl semicircles interlinked by two azo joints. These macrocycles were assembled from ni- tro-functionalized m-terphenyl moieties through reductive dimerization. The semicircles were assembled through Suzuki cross-coupling reactions. The molecular weights of the macrocycles were determined by vapour pressure osmome- try, because mass spectrometry failed in the cases of 2 and 3. The E - Z photoisomerization reactions were analysed by UV/Vis spectroscopy complemented by JH NMR studies. A very slow thermal back-reaction indicated considerable stabilization of the Z isomer. The reduced efficiency of the thermal back-reaction probably arises from the reduced degree of freedom due to the mechanical interlinking of the two azo groups. The photostationary state consisted of all-Z (85%) and all-E isomers (15 %). The E - Z transformation induced by irradiation displayed simple exponential kinetics, which indicates pairwise switching of the two azo groups in a macrocycle, at least on the timescale under investigation.

Synthesis and optical properties of novel blue fluorescent conjugated polymers

In the present paper we describe new approaches towards the synthesis of conjugated polymers with defined conjugation length, resulting in a blue or green fluorescence. The new approach reported here is to use 1,3-phenylene (type 1) and 10,10'-bianthrylene (type 2) bridges of conjugated segments such as stilbenes and thiophenes which can easily be varied to further change the optical properties.
