“…For a successful screening and subsequent data analysis highly pure compounds are of the utmost importance. The analysis of the data sets encompassed the structure ± property relationships [4] which should make a rational design of novel organic materials with desirable properties possible.In this study we concentrate on fluorescent dyes of the coumarin type which are of interest not only because of their pharmacological activity [6] but also because of their applications as laser dyes, [7] fluorescent labels [8] (e.g. in biological applications), emission layers in organic light-emitting diodes (OLED), [9] and as optical brighteners.…”

“…Consequently, we asked whether the concepts of combinatorial chemistry are applicable to the development of novel organic materials? We report here and in the following correspondence [4] the efficient generation and screening of single-compound libraries containing fluorescent dyes [5] and p-conjugated oligomers; with these studies we show that the concepts of combinatorial chemistry can be successfully applied to organic materials using rapid parallel and mix-and-split synthesis in solution and also on solid supports. For a successful screening and subsequent data analysis highly pure compounds are of the utmost importance.…”

“…In contrast, addition of electron donating groups at the 4-, 6-, or 7-positions or electron withdrawing groups at the 3-position can shift the fluorescence band to longer wavelengths. [11][12][13] Based on this principle, Zhou and Fahrni prepared the non-fluorescent 1, where a 7-alkynyl group was introduced to quench the fluorescence of the coumarin core. After CuAAC reaction with the azide 2, the fluorescence could be restored by the formation of the triazole compound 3 (Scheme 1a).…”

#Thanks a lot, Prof. Hans Viertler, for everything you taught me: a plenty of good chemistry, specially organic chemistry and electrochemistry… Thanks for the good examples to be followed and the mistakes and bad things to be avoided… and finally citing Carl Gustav Jung as followed, thank you for helping me to transform myself in the chemist I am now… " Recebido em 24/3/10; aceito em 27/8/10; publicado na web em 25/10/10 THIOPHENE-BASED OLIGOMERS AND POLYMERS: SYNTHESES AND APPLICATIONS. In this review we summarize recent synthetic investigations about the preparation of oligothiophenes and polythiophenes, the most important π-conjugated organic materials for applications in electrochromic and electroluminescent devices. It is showed that many interesting and novel functionalized oligothiophenes have been synthesized by convenient coupling strategies (Heck, Kumada, Negishi, Suzuki, Stille and Ullmann) and oxidative coupling methods. Synthesis of polythiophenes are also presented and described according to chemical and electrochemical polymerization methodologies. The description of these noteworthy synthetic methods illustrates how important and promising are the interdisciplinary approaches in the obtaining of oligothiophenes and polythiophenes.Keywords: oligomeric and polymeric thiophenes; syntheses; conjugated polymers. INTRODUÇÃOOs polímeros conjugados (PCs) são conhecidos como "metais sintéticos" devido a suas propriedades elétricas, magnéticas, eletrô-nicas e ópticas semelhantes aos dos metais; as propriedades de um polímero convencional (flexibilidade, processabilidade e formação de filmes finos, boa estabilidade térmica, etc.) e as propriedades de um semicondutor combinadas em um único material resultam em polímeros para aplicação no campo da eletrônica orgânica. A incontestável importância científica atual desta classe de materiais pode ser percebida pela concessão do Prêmio Nobel de Química de 2000 para Heeger, McDiarmid e Shirakawa por suas pesquisas com PCs. 1 É digno de nota que, quando estes materiais são estimulados eletricamente, podem ter sua cor variada de forma reversível ou mesmo emitir luz visível, o que possibilita a sua aplicação em diversos dispositivos eletrocrômicos 2 ou diodos emissores de luz orgânicos (OLEDs -Organic Light Emission Diodes). Dentre outras possibilidades de aplicação, pode-se citar o desenvolvimento de condutores elétricos, células fotovoltaicas poliméricas, transistores orgânicos, 3,4 anticorrosivos, 5,6 materiais eletrocrômicos, 7 baterias recarregáveis, 8 etc.Em meio aos diversos PCs pesquisados para o desenvolvimento dos dispositivos eletrônicos orgânicos, tais como politiofenos (1), polipirróis (2), polianilinas (3), 9,10 polifenilenovinilenos (4) 11 (Figura 1), destacam-se os politiofenos e seus derivados, que são os materiais mais estudados nesta área. 2 A possibilidade de aplicação dos politiofenos em dispositivos eletrocrômicos é conhecida desde 1983 12-15 e, em 1986, com a primeira síntese descrita de polialquiltiofenos com processabilidade e projeção a nível...
