Toluene (BDH) was predried over 4-A˚ molecular sieves and distilled from sodium benzophenone
ketyl immediately prior to use.Dichloromethane
(DCM) was distilled from calcium hydride before
use.All other chemicals were purchased from
Aldrich and used as received without further
purification.N,N0-di(n-butyl)-1,6,7,12-tetrakis(4-
tert-butylphenoxy)-3,4,9,10-perylenetetracarboxylic
bisimide was prepared according to the
methods described in the literature.4-Ethynylbenzonic
acid was synthesized by palladiumcatalyzed
coupling reaction of trimethylsilylacetylene
with methyl 4-bromobenzoate followed by
base-catalyzed desilylation.11-Phthalimido-1-
phenyl-1-undecyne,poly(11-phthalimido-1-
phenyl-1-undecyne) (P8; Mw 22,700; Mw/Mn 1.5),
and poly(11-amino-1-phenyl-1-undecyne) (P11;
Mw 11,500; Mw/Mn 1.4) were prepared according
to our previous article.
Instrumentation
IR spectra were measured on a Perkin–Elmer
