site. If Ru(II) terpyridine complexes are prime building blocks for structural reasons, the short lifetime of their excited state prevents their use as a harvesting center in light antennae. In this paper, we present new polynuclear assemblies, based on Ru(II)-terpyridine units where delocalization of the excited state is combined with an antenna effect. As a consequence, complexes C1–C3 display long-lived

A 3D trismetallo-macromolecule was assembled with a stepwise synthesized key metallo-organic ligand, which was created by a reaction on complex strategy.
1D and 2D NMR, ESI-MS, and transmission electron microscopy. Furthermore, this metallo-nanosphere was observed to hierarchically self-assemble into berry-type structures in an acetonitrile/methanol mixture, by virtue of counterion-mediated attractions. The functional molecular metallo-nanosphere presented here expands the reach of terpyridine coordination systems into molecularcontainers and other

The application further relates to a strongly-polarized molecule-graphene molecule heterojunction, and a single molecule field effect transistor comprising a substrate, a gate, a dielectric layer and the strongly-polarized molecule-graphene molecule heterojunction; and the dielectric layer is located between the gate and the strongly-polarized molecule-graphene molecule heterojuction. The single molecule field effect transistor provided by the application can realize highly-efficient gate modulation.

aggregation-induced emission (AIE) effect based on the restriction of intramolecular rotation (RIR). Meanwhile, boron-dipyrromethene (BODIPY) tends to emit intense fluorescence with high quantum yields. Herein, we combined TPE, BODIPY and terpyridine (TPY) into one system to study the emissive behaviour of organic building block as well as a self-assembled metallo-supramolecule. The TPY and BODIPY substituents
