Aggregation-Induced Emission and Photocyclization of Poly(hexaphenyl-1,3-butadiene)s Synthesized from 1 + 2 Polycoupling of Internal Alkynes and Arylboronic Acids

A new polymerization method for in situ generation of luminescent polymers with aggregation-induced emission characteristics from readily prepared or commercially available reactants was developed in this work. The 1 + 2 polycoupling of internal alkynes and arylboronic acids took place under mild reaction conditions and was tolerant to moisture, air, and monomer stoichiometric imbalance, furnishing poly(hexaphenyl-1,3-butadiene)s (PHBs) with partially or wholly conjugated structures in satisfactory yields. All the PHBs showed good solubility, thermal stability, and film-forming ability. Their optical properties could be easily tuned by proper monomer design and external perturbation. The PHBs underwent active photocyclization in both solution and solid states, converting them to poly(dihydronaphthalene)s. Such a property made them promising materials for fabricating luminescent photopatterns. A new mechanistic pathway was proposed as supplementary to explain the aggregation-induced emission (AIE) phenomenon by studying the emission of PHBs and the corresponding model compound.

Simple Modifications for the Facile Preparation of 1,1,2,3,4,4-Hexaaryl-1,3-butadienes

A facile preparation of 1,1,2,3,4,4-hexaaryl-1,3-butadienes which are important molecules due to their aggregation-induced emission (AIE) activity was achieved by simple modifications of the reaction conditions reported in the previous work. In this react

Zirconoarylation of alkynes through p-chloranilpromoted reductive elimination of arylzirconates

A novel method for the zirconoarylation of alkynes was developed. TCQ-promoted reductive elimination of arylzirconate [LiCp2ZrAr(RC=CR) ], which was prepared by the reaction of zirconocene-alkyne complexes with aryllithium compounds, afforded trisubstituted alkenylzirconocenes. This reaction can afford multi-substituted olefins with high stereoselectivity.
