Synthesis of C60 end-capped poly(4-diphenylaminostyrene): Addition of poly(4-diphenylaminostyryl)lithium to C60

Bipolar polymer semiconductor blends of C60‐end‐capped poly(4‐diphenylaminostyrene) and poly(4‐diphenylaminostyrene): One‐pot synthesis and charge‐transport properties

“…We have previously reported that in the reaction of an excess amount of the PDASLi/TMEDA system with C 60 , only one PDASLi molecule selectively binds to one C 60 molecule at the polymer chain end. 13 The addition of a second PDASLi molecule to C 60 does not occur. As a result, C 60 –PDAS/PDAS blends are formed in the reaction mixture (Scheme ).…”

“…Recently, we attempted the anionic polymerization of DAS to obtain PDAS with a well‐defined polymer chain structure. 12–15 As a result, the first successful example of the living anionic polymerization of DAS with the tert ‐butyllithium ( t ‐BuLi)/ N,N,N ′, N ′‐tetramethylethylenediamine (TMEDA) system was discovered (Scheme ), 12 and the stereoregularity of PDAS was also revealed. 12, 14 Subsequently, we examined the grafting reaction of the poly(4‐diphenylaminostyryl)lithium (PDASLi)/TMEDA system with a fullerene (C 60 ), and C 60 ‐end‐capped poly(4‐diphenylaminostyrene) (C 60 –PDAS), which consists of one PDAS molecule bonded to one C 60 molecule at the polymer chain end, was successfully prepared (Scheme ).…”

Electrogenerated networks from poly[4-(diphenylamino)benzyl methacrylate] and their electrochromic properties

“…Polymerization via reversible addition-fragmentation chain transfer (RAFT) can be only readily mediated using xanthates or dithiocarbamate as the chains transfer agent [16,[18][19][20][21] or nitroxide-mediated polymerization (NMP) [22] and by atom transfer radical polymerization (ATRP) [23,24]. Several attempts for synthesis of vinyl polymers having triphenylamine as pendant groups, using controlled radical polymerization (NMP [25][26][27][28] and RAFT [29][30][31][32]) or living anionic route [33][34][35][36][37][38][39][40] have been recently reported. However, the controlled radical polymerization of triphenylamine-based (meth) acrylate monomers was less studied until now, only a paper revealing the group transfer polymerization of 4-(dimethylamino)benzyl methacrylate was published [41].…”

Effect of polymer chain structure on electroluminescence of poly(4-diphenylaminostyrene)/Alq3 blend films

“…To our knowledge, only the dependence of the glass transition temperature on the degree of polymerization of PDAS has been examined by Behl et al 4 Recently, we attempted the anionic polymerization of DAS to obtain PDAS with a well-defined polymer chain structure. [12][13][14] As a result, the first successful example of the living anionic polymerization of DAS using the alkyllithium/amine system was discovered (Scheme 1). The method involved the synthesis of homopolymers and block copolymers with narrow-range polydispersity indices, controlled molecular weight and well-defined polymer chain structures.…”
