    Abstract: Image formation via photoinduced fluorescence changes in a polymeric medium with two-photon fluorescence readout of a multi-layer structure. Fluorophore-containing polymers, possessing one or more basic functional groups, underwent protonation in the presence of a photoinduced acid generator upon exposure to a broad-band UV light source or fast-pulsed red to near-IR laser irradiation. Solution studies demonstrated formation of monoprotonated and diprotonated species upon irradiation, each resulting in distinctly different absorption and fluorescence properties. The fluorescence of the original, neutral, fluorophore was reduced upon monoprotonation, leading to a concomitant increase in fluorescence at longer wavelengths due to the monoprotonated form, the basis for multichannel data readout.

  • Patent number: 6897341
    Abstract: A bis(aminostyryl)naphthalene compound represented by the general formula [I] or the like below. (where R2 and R3 each denotes an unsubstituted aryl group; R1 and R4 each denotes an aryl group having a specific substituent such as methoxy group; and R5 and R6 each denotes a cyano group or the like.) A process for producing a bis(aminostyryl)naphthalene compound represented by the general formula [I] by condensation of, for example, 4-(N,N-diarylamino)benzaldehyde with diphosphonic ester or diphosphonium. The bis(aminostyryl)naphthalene compound emits intense yellow or red light. The process permits efficient production of the bis(aminostyryl)naphthalene compound.

  • Publication number: 20040211113
    Abstract: Disclosed herein is a process for the preparation of alkylated diarylamines comprising adding to said diarylamine an olefin mixture containing highly reactive fractions, as well as fractions exhibiting a relatively lower chemical reactivity, in the presence of an acidic clay catalyst at a temperature low enough to prevent substantial deactivation of the catalyst until the addition is complete and then increasing the temperature to increase the alkylation rate of the less reactive fractions.
