|  |  | 2,4,7,9-Tetramethyl-5-decyne-4,7-diol Usage And Synthesis | 
 | Chemical Properties | 2,4,7,9-Tetramethyl-5-decyne-4,7-diol is white to pale yellow low melting mass |  | Uses | 2, 4, 7, 9-tetramethyldec-5-yne-4,7-diol may be used to dope poly[9,9-bis(6′-(diethanolamino)hexyl)-fluorene],that acts as an interfacial layer in a heterojunction solar cell. |  | Uses | 2,4,7,9-Tetramethyl-5-decyne-4,7-diol is an acetylene glycol derivative used in water-based coatings and has both antifoaming and surfactant properties. It is highly toxic and have been found in acrylic adhesives used for food packaging multilayers manufacturing. |  | General Description | 2, 4, 7, 9-tetramethyldec-5-yne-4,7-diol is a well-known acrylic adhesive. It has amphiphilic characteristics. It is used a dopant in a heterojunction solar cell, it assists in the formation of a homogeneous interfacial layer over the photoactive layer. Doping results in decreasing the absorption of photons in the underneath photoactive layer, thereby in enhancing the photocurrent density. |  | Flammability and Explosibility | Nonflammable |
