Programmable In-Situ Co-Assembly of Organic Multi-Block Nanowires for Cascade Optical Waveguides.

Organic heterostructures (OHs) with multi-segments exhibit special optoelectronic properties compared with monomeric structures. Nevertheless, the synthesis of multi-block heterostructures remains challenging due to compatibility issues between segment parts, which restricts their application in optical waveguides and integrated optics. Herein, we demonstrate programmable in-situ co-assembly engineering, combining multi-step spontaneous self-assembly processes to promote the synthesis of multi-block heterostructures with a rational arrangement of three or more segments.

Oxalierpenes A and B, Unusual Indole-Diterpenoid Derivatives with Antiviral Activity from a Marine-Derived Strain of the Fungus .

Oxalierpenes A and B ( and ), two unusual indole-diterpenoid derivatives, were obtained from the marine-derived fungus . The absolute configurations of and were elucidated by calculated TDDFT ECD and DP4plus methods. Oxalierpene A () represents the first indole-diterpenoid derivative with a five-membered ring of 4-hydroxy-5,5-dimethyldihydrofuran-3-one as a side chain.

Realization of Single-Phase White-Light-Emitting Materials with Time-Evolution Ultralong Room-Temperature Phosphorescence by Coordination Assemblies.

Two Cd-based supramolecular coordination polymers, [Cd(CzIP)(DMF)] () and [Cd(CzIP)(DMF)] (), were synthesized by using 5-(carbazol-9-yl) isophthalate (CzIP) as ligands. These two compounds exhibit multiple luminescence emissions; apart from fluorescence, time- and temperature-dependent ultralong phosphorescence (RTP) were also achieved under room conditions. Significantly, compound has a long-lived afterglow of 0.
