A co-crystal was obtained based on donor–acceptor interactions. The obvious charge transfer from the linear donor to the triangular acceptor units results in a quasi-two-dimensional CT complex with excellent near-infrared photothermal conversion efficiency. The co-crystals further acted as an excellent photothermal material in seawater desalination. [ABSTRACT FROM AUTHOR]

A well-defined crystalline cyano-functionalized graphdiyne (CN-GDY) is synthesized at a liquid/liquid interface through alkyne–alkyne coupling reactions. The configurations and nanostructures of CN-GDY were well characterized by TEM, SEM, AFM, XPS, and Raman spectroscopy. HR-TEM and selected area electron diffraction (SAED) in combination with structure simulation firmly revealed a 9-fold stacking mode for CN-GDY. [ABSTRACT FROM AUTHOR]

A series of sulfide and sulfone substituted perylene diimides (PDIs) with different LUMO levels covering a range of 0.72 eV were synthesized through simple sulfur redox chemistry. The LUMO level of phenylsulfone substituted PDI reached a record-breaking −4.75 eV. In addition, the maximum emission ranged from 540 to 692 nm. [ABSTRACT FROM AUTHOR]

The circular dichroism and circularly polarized luminescence of achiral inorganic Eu-containing clusters in an electrostatically coassembled supramolecular assembly were induced by a cationic chiral copolymer with the help of an enhanced electromagnetic field generated by Ag nanoparticles.

We have designed and synthesized two porphyrin containing two-dimensional (2D) polymers based on the imine linkage. Both the 2D polymers are revealed to be 2D organic semiconductors with band gaps of around 1 eV. STM characterization reveals that the rigidity and affinity of building blocks to the surface has essential effects on the topology of the 2D polymers. [ABSTRACT FROM AUTHOR]
