CAS NO.: 373596-08-8;6,13-bis((triisopropylsilyl)ethynyl)pentacene. PROPERTIES: This silyl-protected pentacene derivative presents as a dark blue solid with a molecular weight of approximately 538.7 g/mol. The 6,13-bis((triisopropylsilyl)ethynyl)pentacene combines a pentacene backbone with two ethynyltriisopropylsilyl groups. It exhibits limited solubility in common organic solvents but dissolves in chlorobenzene and o-dichlorobenzene. Stability characterization reveals sensitivity to atmospheric moisture and oxygen, necessitating storage at 2-8 degree Celsius under inert atmosphere in sealed glass containers. Handlers should employ full-face respirators and use PTFE-lined transfer devices. Skin absorption may cause systemic toxicity requiring immediate medical attention. Inhalation poses risk of pulmonary fibrosis; treatment includes corticosteroid therapy. Eye contact requires 15 minutes of rinsing followed by ophthalmology consultation. Waste should be processed through activated carbon prior to disposal. APPLICATIONS: The 6,13-bis((triisopropylsilyl)ethynyl)pentacene serves as a key intermediate in organic electronics and specialty materials. Its silyl-protected ethynyl groups provide handles for chemical functionalization and improved solubility. Research teams utilize this compound for creating solution-processable organic semiconductors. The ethynyl groups undergo click chemistry reactions for creating covalent conjugates with biomolecules. In materials science, its controlled solubility facilitates fabrication of organic thin-film transistors with enhanced mobility.
