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.

Application

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.

The suitability of an acrylic adhesive used on food packaging was studied. Six potential migrants were identified using GC-MS and UPLC-QTOF. Five compounds were intentionally added (2-butoxyethanol and 2,4,7,9-tetramethyl-5-decyne-4,7-diol 10 (TMDD) and TMDD ethoxylates). One of the compounds identified as
