Synthesis of C₆₀‐bonded polystyrene initiated with C₆₀Cl_n/Ni(naph)₂/P(Ph)₃

Abstract

A linear-shaped polystyrene with C 60 core was prepared with a novel initiator system, C 60 Cl n (n average value is 20)/Ni(naph) 2 /P(Ph) 3, and T p was 130°C. The results of gel-permeation chromatography detected by UV detector and fluorescence spectrum of C 60 -PSt demonstrated that C 60 was chemically bonded to polystyrene. The linear increasing of molecular weights (M n,GPC ) with conversion indicated that this novel initiator system had some characters of living polymerization. A bathochromic shift was found in the UV-vis spectra curves with increasing concentration of C 60 -PSt in THF solution.

Fullerene Polymers: Synthesis and Properties

“…In addition to the anionic polymerization, PS chains have been grafted onto C 60 to form starlike polymers via free radical, ATRP on C 60 , C 60 Cl n , as well as through “living” radical polymerization . The latter issue has been well developed by Fukuda et al, who reported on the synthesis of 1,4-dipolystyryldihydro[60]fullerene starting from narrow polydispersity polystyryl adducts TEMPO-end-capped (Scheme ). 138a-c

Fullerene Polymers: Synthetic Strategies, Properties and Applications

“…In this way, styrene (37) and N-vinylcarbazole (38) have been polymerized obtaining the corresponding polystyrene (PS) and polyvinylcarbazole (PVK) star polymers as depicted in Fig. 10.…”

Fullerenes

“…174 A linear polystyrene with a [60]fullerene core results when highly chlorinated [60]fullerene is used as part of a novel polymerisation initiator. 175 Fluoroalkyl [60]fullerene end-capped co-oligomers have been prepared and shown to effectively solubilise [60]fullerene in ionic liquids. 176 Pendant [60]fullerene groups are arranged in helical arrays on optically active poly(phenylacetylene)s 177 and photoactive polyacetylenes with pendant [60]fullerene groups have been prepared.…”
