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