“…This would indicate that the molecules associate at the aromatic core. T6.2 also associates with silica that is typical for oligothiophenes . This association affects the packing of oligomers at the surface of SiO 2 transistor gate dielectrica.…”

Three β,β'-dihexylsexithiophenes were synthesized, one without end group modification (T6.1), one with dialdehyde (T6.2) and one with diester (T6.3) end-capping. Their properties were investigated by cyclic voltammetry and Ultraviolet-visible spectroscopy, and it was found that while they were nonconducting in undoped form, the conductivity reached 0.001 S cm −1 (T6.1), 0.017 S cm −1 (T6.2), and 0.003 S cm −1 (T6.3) when doped with iodine vapor. The solubilities of T6.2 and T6.3 in chloroform were excellent, whereas the solubility of T6.1 was low and in line with earlier literature values. Moreover, the studies revealed that T6.2 is also highly soluble in tetrahydrofuran. For the dialdehyde end-capped β,β'-dihexylsexithiophene T6.2 association constants for self-association in chloroform and with silica were determined to be 1.6 and 2.3 (mol/kg) −1 , respectively. In contrast, the two other oligothiophenes did not show such associations.

“…Muccini and coworkers demonstrated that the mechanism of energy transfer in a-sexithienyl is highly sensitive to the molecular environment. [53] Through comparing sub-mono-layer and lamellae architectures they were able to relate features seen in the photoluminescence spectra to precise structural topologies.…”

Four new thermally stable and optically active poly(amide-imide)s (PAI)s with good inherent viscosities were synthesized from the direct polycondensation reaction of N,N-(pyromellitoyl)-bis-L-α-amino acids with 3,5-diamino-N-(3,4-dihydroxy-phen-ethyl)benzamide in a medium consisting of a molten salt, tetrabutylammonium bromide, and triphenyl phosphite as the activator. The polymerization reactions produced a series of novel PAIs containing dopamine segment in the side chain in high yield with inherent viscosities between 0.33 and 0.49 dL/g. The obtained polymers were typically characterized by means of FT-IR, 1 H NMR spectroscopy, elemental analyses, powder X-ray diffraction, field emission scanning electron microscopy, inherent viscosity, and solubility tests. Thermal properties and flame retardant behaviour of the PAIs were also investigated using thermal gravimetric analysis (TGA and DTG) and limiting oxygen index (LOI). Data obtained by thermal analysis revealed that these polymers showed good thermal stability. Furthermore, high char yield in TGA and good LOI values indicated that the obtained polymers were capable of exhibiting good flame retardant properties.
