Abstract:
The fluorescent gel of silver-complex is provided to form gel and express the remarkably increased and red-shifted fluorescence by forming the network structure of fibers through binding of silver ion to the AIEE(aggregation-induced enhanced emission)-active ligand, thereby being applicable to the fluorescence sensor. The manufacturing method of the new pyridine-containing trifluoromethyl-based cyano stilbene derivative(CN-TFMBPPE) functioning as the silver-binding monodentate ligand comprises the steps of: refluxing the toluene/iso-propanol /water(2N K2CO3) solution under the tetrakis(triphenylphosphine) palladium(0) catalyst through the Suzuki reaction for 7 hours to prepare aldehyde 1; refluxing the THF/water(2N K2CO3) solution under the tetrakis(triphenylphosphine) palladium(0) catalyst through the Suzuki reaction for 12 hours to prepare the benzyl cyano derivative 2; and reacting the t-butyl alcohol/THF solution under the tetrabutylammonium hydroxide catalyst through the Knoevenagel reaction at 50 deg. C for 2 hours.

Abstract:
A rewritable fluorescence memory film, and a non-destructive writing/reading/erasing method using the same are provided to repeat data recording and erasing on a fluorescence memory film of polymer composite containing fluorescent material with high Stokes' shift and BTE photochromic compound. A rewritable fluorescence memory film is formed by applying coating material on a substrate, wherein the coating material contains 10 to 30wt.% composite of fluorescent material and photochromic compound and 90 to 70wt.% matrix polymer dissolved. The fluorescent material, which is excited-state intramolecular proton transfer compound, has a maximum absorption wavelength in a range of 410 to 430nm, a maximum fluorescence emission wavelength in a range of 450 to 700nm, and a difference between the maximum absorption wavelength and maximum fluorescence emission wavelength(Stokes' Shift) in a range of 20 to 290nm. The photochromic compound emits color under irradiation of ultraviolet rays having a wavelength of 400nm or less.
