Two-Photon Absorption Properties of Diacetylene Derivatives Confined in the Interlayer Space of a Synthetic Saponite(Special Report)

Abstract

Diacetylene derivatives, 1-methyl-4-[biphenyl-4-(1,3butadiyn4-yl)] pyridinium triflate (monoBBP) and 4,4'-[biphenyl-4,4'-bis(1,3-butadiyn-4-yl)]bis(1-methylpyridinium) ditriflate (bisBBP) were synthesized. We fabricated composites consisting of the diacetylene derivatives and synthetic saponite. The two-photon absorption (TPA) characteristics of the diacetylene derivatives confined in the interlayer space of synthetic saponite were compared to those in dimethylsulfoxide (DMSO). The maximum values of TPA cross-section of monoBBP and bisBBP confined in the interlayer space of synthetic saponite were 7.3 and 13.5 times larger than that in DMSO, respectively.
