“…Recently, solid‐state polymerization of 2,5‐dihalothiophene derivatives under solventless and catalyst‐free conditions has attracted significant attention for the synthesis of highly ordered polymers and macroscopic polymer single crystals 14, 63–65. In 2003, Skabara and coworkers demonstrated the applicability of this method for the preparation of bromine‐doped PEDTT by heating the crystal of DBEDTT 14. However, no detailed synthetic information and electrical conductivity of PEDTT were given.…”

BACKGROUND: Magnetic resonance imaging (MRI) has been used to supplement screening mammography and clinical breast examination (CBE) in women who are at high risk of developing breast cancer. In this study, the authors investigated the efficacy of alternating screening mammography and breast MRI every 6 months in women who had a genetically high risk of developing breast cancer. METHODS: A retrospective chart review was performed on all women who were seen in a high-risk breast cancer clinic from 1997 to 2009. Patients with breast cancer gene (BRCA) mutations who underwent alternating screening mammography and breast MRI every 6 months were included in the study. Mammography, ultrasonography, MRI, and biopsy results were reviewed. RESULTS: Of 73 patients who met the study criteria, 37 had BRCA1 mutations, and 36 had BRCA2 mutations. Twenty-one patients (29%) completed 1 cycle of mammography and MRI surveillance, 23 patients (31%) completed 2 cycles, 18 patients (25%) completed 3 cycles, and patients 11 (15%) completed !4 cycles. The median follow-up was 2 years (range, 1-6 years). Thirteen cancers were detected among 11 women (15%). The mean tumor size was 14 mm (range, 1-30 mm), and 2 patients had bilateral cancers. Twelve of 13 cancers were detected on an MRI but not on the screening mammography study that was obtained 6 months earlier. One cancer (a 1-mm focus of ductal carcinoma in situ) was an incidental finding in a prophylactic mastectomy specimen. One patient had ipsilateral axillary lymphadenopathy identified on ultrasonography but had no evidence of lymph node involvement after neoadjuvant chemotherapy and surgery. CONCLUSIONS: In women who were at genetically high risk of developing breast cancer, MRI detected cancers that were not identified on mammography 6 months earlier. Future prospective studies are needed to evaluate the benefits of this screening regimen.

“…In the past 20 years, the electrochemical homopolymerization of compounds containing 3,4‐ethylenedithiathiophene (EDTT) units, as listed in Scheme , has been studied in detail 6, 9–11, 16, 18, 20, 22. Other methods, such as chemical oxidative and solid‐state homopolymerization and, recently, Stille coupling, have also been reported 4, 7, 23–26. However, PEDTT and its derivatives achieved from these methods are usually powders.…”

The chemical oxidative copolymerization of 3,4-ethylenedithiathiophene (EDTT) with 3,4-ethylenedioxythiophene (EDOT) and 2 0 -hydroxymethyl-3,4-ethylenedioxythiophene in a poly(styrene sulfonic acid) aqueous solution was successfully carried out to form stable, dark blue colloidal dispersions in water. Coating these dispersions onto polypropylene substrates led to the formation of free-standing copolymer films. The mechanical, electrical, and thermoelectrical properties of these films were investigated; the films showed superior properties in comparison with those of poly(3,4-ethylenedithiathiophene) (PEDTT)/poly(styrene sulfonate) (PSS). The copolymer film based on EDTT and EDOT achieved a high electrical conductivity (8.2 Â 10 À2 S cm À1 ) at 298 K; this could be improved about 10 times through the addition of dimethyl sulfoxide (DMSO) or DMSO/isopropyl alcohol into the polymer dispersion with almost constant Seebeck coefficients of about 9 lV K À1 . On the contrary, these additives had almost no effect on the conductivity of PEDTT/PSS. The structure and morphology of the polymer films were studied by X-ray diffraction and SEM analyses.

“…Comparison of molecular structure and properties between PEDOT and PEDTT has been reported in the literature [11][12][13][14][15][16][17]. It shows that PEDTT presents a higher oxidation potential, larger band gap and poor electro-conductivity, while its cathode activity remains unknown to date.…”
