摘要： A Pd-catalyzed single-step C-H arylation of dioxythiophene derivatives bearing unprotected reactive functional groups (-OH, -COOH, -N 3 ) in a phosphine-free manner has been developed. Various dioxythiopene-based oligoarenes with extended π-conjugation are obtained with good yields (up to 90%). These oligoarenes display suitable optical properties (absorption and emission maxima, quantum yields) and contain reactive functional groups suitable for further conjugations with bioactive molecules. This new methodology is step economical (fewer synthetic steps) and environmentally friendly (no toxic metal-containing by-products) and the oligoarenes synthesized are potentially applicable for bio-labeling, bioimaging, and biosensing. A phosphine-free C-H arylation of dioxythiophenes bearing unprotected functional groups affords oligoarenes with good yields. 出版日期： 2015-07-28 資源來源： Royal Society of Chemistry 識別號： ISSN: 1477-0520 識別號： EISSN: 1477-0539 識別號： DOI: 10.1039/c5ob00705d
