We report here the terpolymerization of butadiene (BD), isoprene (IP), and styrene (St) by a half-sandwich scandium catalyst bearing an unsubstituted cyclopentadienyl ligand, (C5H5)Sc(CH2C6H4NMe2-o)2/[Ph3C][B(C6F5)4], which afforded for the first time the BD–IP–St terpolymers containing high cis-1,4-BD and high cis-1,4-IP units and atactic polystyrene blocks. The copolymerization of BD and IP by this...
A series of multicoumarin-functionalized dendrigraft polybutadienes with linear-comb or star-comb topology were synthesized from generation 0 to 3 (LGn and SGn respectively, n = 0–3) to investigate the dendritic effects on photophysical and fluorescence properties. From the results of SEC-TALLS, SEC and ubbelohde viscometer, the polymer architecture converted from one- or two-dimensional structure...
Water-soluble sulfonated poly(diphenylamine) (SPDPA) was synthesized and applied as a hole injection layer (HIL). It was characterized in terms of 1 H NMR, 13 C NMR, elemental analysis (EA), UV–vis, Raman, ultraviolet photoelectron spectroscopies (UPS) and TGA thermal stability measurement. The high transparency in visible region and acceptable conductivity were beneficial as HIL material...
