Search for Squaraine Derivatives That Can Be Sublimed without Thermal Decomposition

To search for sublimable squaraine (SQ) dyes for fabricating thin films under vacuum, we have synthesized a series of 2,4-bis[4-(N,N-dialkylamino)-2,6-dihydroxyphenyl]squaraines [SQ(OH)4] and studied their properties. The investigation of the behavior of their Langmuir films at the air−water interfa... View More
