7,7,8,8-Tetracianochinodimetano

Descrizione:

7,7,8,8-Tetracianochinodimetano (TCNQ) è un composto organico altamente coniugato noto per le sue forti proprietà di accettazione degli elettroni. Presenta una struttura di quinodimetano con quattro gruppi ciano (–CN) attaccati, che migliora significativamente la sua affinità elettronica. TCNQ è tipicamente un solido blu scuro a temperatura ambiente ed è solubile in vari solventi organici, rendendolo utile in diverse applicazioni chimiche. La sua alta affinità elettronica gli consente di formare complessi di trasferimento di carica con donatori di elettroni, il che è prezioso nell'elettronica organica e nella scienza dei materiali. TCNQ è anche utilizzato nella sintesi di polimeri conduttivi e come reagente nella sintesi organica. Inoltre, presenta interessanti proprietà ottiche, tra cui una forte assorbimento nella regione ultravioletta-visibile, che può essere sfruttata in applicazioni fotoniche. A causa della sua stabilità e reattività, TCNQ viene spesso maneggiato con cura in ambienti di laboratorio. In generale, TCNQ è un composto significativo nel campo della chimica organica e della scienza dei materiali, contribuendo ai progressi nei materiali e nei dispositivi elettronici.
