Synthesis of fulvene-containing boron complexes with aggregation-induced emission and mechanochromic luminescence.

Two donor-acceptor motif fulvene-containing boron complexes were synthesized with fulvene diketonate boron difluoride (FDB) as the organic acceptor. Both difluoroboron complexes present aggregation-induced emission (AIE) properties and cell tracing function with excellent biocompatibility. And mechanochromic luminescence has been accomplished by the synthesis, isolation and characterization of BL2.

A benzothiadiazole-based covalent organic framework for highly efficient visible-light driven hydrogen evolution.

We demonstrate herein a newly designed benzothiadiazole-based covalent organic framework through an imine linkage with high crystallinity, excellent chemical stability and significant light absorption ability, which was further applied as a high-performance platform for efficient visible-light driven hydrogen evolution.
