Abstract—This paper focuses on the fabrication of organic–inorganic composite materials with opto-
electronic functionality based on carbon nanotubes (CNTs) by chemical and physical modiﬁcations.
The one-dimensionally (1D) ordered composites of rare earth phthalocyanine compounds (RePc
capsulated by MWCNTs were obtained using a simple capillary ﬁlling method. The CNT-templated
assembly of RePc
nanowires was performed by a phase-separation method. Two other kinds of
organic–inorganic 1D-ordered optoelectronic composites were prepared using the template method:
coating MWCNTs with a ﬂuorescent poly(triphenylamine) related co-polymer can be realized via a
facile phase-separation strategy; 1D hybrid of bamboo-shaped CNTs covalently bound to RePc
relationship between the microstructure of the obtained 1D-ordered composites and optoelectronic
properties was studied, and it was found that these ordered composites exhibited enhanced photocon-
ductivity due to the charge transfer between the composite components.
Keywords: Carbon nanotubes; organic/inorganic composites; optoelectronic properties.
Recently, carbon nanotubes (CNTs) have attracted more and more attention due to
their remarkable optical, electrical, thermal, magnetic and mechanical properties.
Many applications have been exploited for CNTs in various ﬁelds, such as ﬁeld-
effect transistors (FETs), organic light-emitting diodes (OLEDs), organic solar cells,
chemical actuators, ultrafast optical switches, tips for scanning-probe microscopes,
and so on [1 –8]. Moreover, consisting of one or more graphene sheets wrapped
around each other in coaxial cylinders with a hollow core, CNTs form a good one-
