Molecular structures have significant impact on the
properties of organic materials. For instance, one crucial issue
for the application of π-conjugated oligomers in organic
optoelectronic devices is their ability to form morphologically
stable and homogeneous films. To fulfill this requirement
and others, several families of molecular architectures have
been exploited, such as starburst molecules with C3symmetry,3 orthogonally fused spiro-type molecules,4 paracy-
clophanes,5 tetrahedral molecules,6 dendrimers,7 and twin
molecules.8 As the most straightforward approach, twin
molecule couples two chromophore halves by either a
flexible alkyl spacer or a rigid aromatic linkage. The
electronic properties of the former are almost the same as
those of the monomer, while the latter allows an extension
of π-electronic conjugation, which increases the effective
conjugation length of the whole molecule.
During the past decades, truxene has been recognized as
the starting material for the construction of larger polyarenes
and bowl-shaped fragment of the fullerenes, liquid crystals,
C3tripod materials in asymmetric catalysis, and chiral
recognition.9We prepared a series of star-shaped oligothio-
phenes-functionalized truxene derivatives and novel π-con-
jugated dendrimers based on truxene, which exhibited unique
NMR behaviors, optical properties, and electrolumines-
cence.10 Herein, we report the initial synthesis of a series of
π-conjugated twin molecules based on truxene, the truxene halves of which are connected by a rigid 9,9-spirobifluore-
nylene or ethynylene or vinylene linkage. We also investigate
optical properties of these molecules, which shed light on
the structure-property relationship of these dimeric mol-
ecules.
