The Uses of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol
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.
The Uses of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol
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.
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.
Hazard
In vivo experiments have shown that 2,4,7,9-Tetramethyl-5-decyne-4,7-diol induced lethargy in a lethal dose inhalation study in rats; tremors and convulsions were induced in a feeding study in dogs. It is an irritant to human skin and eyes, as well as a neurotoxic hazard to the rest of the central nervous system.
