A novel benzoxazine-containing temperature T-sensitive fluorescent polyfluorenes (BluePF-BZ) had been prepared. A benzoxazine monomer (BHPF-paa) was firstly synthesized with 9,9-Bis(4-hydroxyphenyl)fluorene, propargylamine and paraformaldehyde through Mannich condensation reaction. The as-prepared BHPF-paa was then incorporated into the preparation of polyfluorenes, and the main-chain BluePF-BZ could...
A novel chiral polymer P1 was designed and synthesized by the polymerization of (S)-2, 2′-binaphthyladiamine (BINAM) derivative monomer (S-M-1) with 2, 5-diiodo-1, 4-dioctyloxybenzene (M-2) via Pd(II)-catalyzed Sonogashira coupling reaction, and P2 could be obtained by the reduction reaction of P1 with NaBH4. Interestingly, the resulting chiral (S)-BINAM-based polymer P1 sensor can act as a “turn...
A novel MgCl 2 -supported Ziegler-Natta catalyst containing 2-isoamyl-2-isopropyl-1,3-propandiol dibenzoate donor for propylene polymerization was studied, and compared with catalysts with different internal donors, such as benzoate, phthalate and diether, in polymerization dynamic behavior, activity, hydrogen response and stereospecificity. It was found that there are two highly isospecific...
