Conjugated polymers

Conjugated polymers are organic macromolecules that are characterized by a backbone chain of alternating double- and single-bonds. Their overlapping p-orbitals create a system of delocalised π-electrons, which can result in interesting and useful optical and electronic properties.

    For the development of wearable and stretchable devices, stretchable and flexible semiconductive materials are desired. To understand the mechanical behavior of structural deformation of polythiophene with disiloxane groups, we performed in situ measurements under stretching using X-ray diffraction of synchrotron radiation and polarized infrared spectroscopy. The behaviors of amorphous region was oriented during the initial deformation, while the orientation of crystallites began after permanent set.

    The synthesis of a novel conjugated polymer containing fused pyridinium units in its main chain is reported. A precursor polymer possessing pyridine and tetrafluorophenylene moieties was reacted in the presence of Lewis acid additives to promote the intramolecular nucleophilic aromatic substitution (SNAr) reaction. The polymer reaction with BE3-OEt2 gave a product polymer soluble in polar organic solvents, and the successful formation of fused pyridinium ring structures was spectroscopically confirmed. The electrochemical and optical properties of the synthesized polymers were also investigated.

    Realizing efficient n-doping in organic thermoelectrics remains a challenge due to dopant-semiconductor immiscibility, poor dopant stability and low doping efficiency. Here, the authors use computer-assisted screening to develop n-dopants for thermoelectric polymers that show record power factors.

    Improving electron transport and stability of n-type organic electrochemical transistors (OECTs) is required to realize a commercially-viable technology for bioelectronics applications. Here, the authors report water-stable doped n-type OECTs with enhanced transconductance and record stability.

    Nanoparticles that access lymphatic vessels and are functionalized with degradable linkers, whose half-lives can be programmed, enable the controlled release of therapeutic cargo in different regions of the lymph nodes, allowing the targeting of otherwise difficult-to-reach lymphocyte subpopulations.

    A germole-containing π-conjugated polymer is prepared from the corresponding tellurophene-containing polymer by its Te–Li exchange reaction using n-butyllithium followed by the reaction with dimethylgermanium dichloride. The low-lying LUMO energy level of the germole-containing π-conjugated polymer is also described.
