A series of new platinum (II) complexes were obtained, where 2-phenylpyridine derivatives are used as the main ligand and 5-substitued tetrazole are used as the auxiliary ligand. Although the complexes with one or without any peripheral flexible around rigid core do not reveal liquid crystallinity, the complexes with three flexible alkoxy chains attached to 2-phenylpyridine and tetrazole display liquid crystalline property. In order to investigate the self-assembly behavior of the liquid crystalline complexes, their polarized luminescence is researched, and the maximum polarization ratio can reach 7.1 at room temperature. Moreover, the ambipolar carrier mobility was measured in these neutral cyclometalated platinum (II) complexes, the electron mobility and hole mobility can reach 3.3 × 10?4 cm2/(V·S) and 6.3 × 10?5 cm2/(V·S), respectively.

Heteroaromatic nitriles are important compounds in drug discovery, both for their prevalence in the clinic and due to the diverse range of transformations they can undergo. As such, efficient and reliable methods to access them have the potential for far-reaching impact across synthetic chemistry and the biomedical sciences. Herein, we report an approach to heteroaromatic C?H cyanation through triflic anhydride activation, nucleophilic addition of cyanide, followed by elimination of trifluoromethanesulfinate to regenerate the cyanated heteroaromatic ring. This one-pot protocol is simple to perform, is applicable to a broad range of decorated 6-ring N-containing heterocycles, and has been shown to be suitable for late-stage functionalization of complex drug-like architectures.
