Shou, Hansen published the artcileFormation of multicolor polymeric objects by laser-initiated photopolymerization, Related Products of catalysis-chemistry, the publication is Journal of Imaging Science and Technology (1995), 39(1), 18-26, database is CAplus.

The formation of multicolor polymeric objects by laser-induced photopolymerization of photocurable compositions is reported. The formation of a colored plastic object results from: (1) a combination of photobleachable initiators that react at different rates as a function of differing wavelengths of irradiation; (2) an indicator and a photoacid-generating compound used in combination with a photocuring process or thereafter; or (3) a photochromic material used in combination with a photopolymerizable monomeric system. The influence of the factors affecting color formation and the photostability of the formed color polymeric film are evaluated.

Hassoon, Salah published the artcileElectron Transfer Photoreduction of 5,7-Diiodo-3-butoxy-6-fluorone with Tetrabutylammonium Triphenylbutylborate and N,N-Dimethyl-2,6-diisopropylaniline, Computed Properties of 2909-77-5, the publication is Journal of Physical Chemistry (1995), 99(23), 9416-24, database is CAplus.

The photoreduction of 5,7-diiodo-3-butoxy-6-fluorone (DIBF) in the presence of the electron donors, tetrabutylammonium triphenylbutylborate (BORATE), and N,N-dimethyl-2,6-diisopropylaniline (DIDMA) was studied in acetonitrile solution The transient phenomena examined using nanosecond laser flash photolysis confirm that the reduction is a one-electron transfer process from the electron donor to the excited triplet state of the dye. Triplet quenching rate constants were measured for BORATE and DIDMA as well as oxygen. The relative quenching rates for oxygen and DIDMA are ¡Ö20:1. The electron transfer rates calculated are 6.7 ¡Á 10⁷ and 1.2 ¡Á 10⁸ s^-1 in the BORATE and DIDMA systems, resp. The dye radical anion (DIBF^?, ¦Ë_max ¡Ö 420 nm) formed by the electron transfer reaction is the only product obtained in the BORATE case. However, with DIDMA the dye “neutral” radical (DIBF^?, ¦Ë_max ¡Ö 360 nm) was detected as the only product. DIBF^? formed after protonation of DIBF^?- by proton transfer from the amino cation radical. This implies that the proton transfer is too fast to measure on the nanosecond time scale. This is the first such observation in these systems. Singlet oxygen formed by oxygen quenching of the dye triplet was found to be quenched by the electron donors via an electron transfer process also. No quenching of DIBF triplet occurred in the presence of the electron acceptor (4-octyloxyphenyl)phenyliodonium hexafluoroantimonate (OPPI). The principal photobleached products detected by HPLC were reduced quinomethines in the DIDMA case and the ammonium salts of the reduced quinomethines in the BORATE case. Reoxygenation of these products regenerates the original dye in a reaction the rate of which depends on the polarity of the solution However, the reoxygenation of the quinomethines is faster than that of their ammonium salts under the same conditions.

Zakrzewska, Anna published the artcile¹³C-NMR based evaluation of the electronic and steric interactions in aromatic amines, Safety of 2,6-Diisopropyl-N,N-dimethylaniline, the publication is International Journal of Molecular Sciences (2005), 6(1-2), 52-62, database is CAplus.

Chem. shifts of the para carbon atoms, ¦Ä(¹³C-4), in a series of aromatic amines were used to calculate the ¦Ò_p, ¦Ò_R and ¦Ò^O_R substituent constants for different amino groups. 1-Pyrrolidino, N-N-di-n-butylamino and N,N-diethylamino groups were found to be the most strong electron-donors. Ortho-Substitution decreases the donor properties of the amino group. The amino groups in 2,6-di-i-propylaniline and N,N-2,6-tetramethylaniline have very weak electron-donor properties. The nitrogen atom in benzoquinuclidine and N,N-dimethyl-2,6-di-i-propylaniline have an electron-acceptor character. The calculated substituent constants of the amino groups studied are consistent with the spectral and reactivity data available in literature. Values of ¦Ä(¹⁵N) cannot be used as a direct measure of electronic effects of the N atom in anilines.

In this work the optical properties of elec. switched transmission gratings fabricated holog. using polymer-dispersed liquid-crystal (PDLC) materials were investigated. It was found that the PDLC mixture can be used to control the diffractive properties of the liquid-crystal composite gratings. In one limit the gratings are highly isotropic and in the other limit the gratings are highly anisotropic with a large birefringence. The exptl. results are compared to theories that include the birefringence of the grating. From theor. fits to the exptl. data, measurements of the liquid-crystal distribution and alignment are obtained.

A general and efficient method for amide bond synthesis has been developed. The method allows for synthesis of tertiary amides from readily available tertiary amines and anhydrides in the presence of FeCl₂ as catalyst and tert-Bu hydroperoxide in water (T-Hydro) as oxidant. Mechanistic studies indicated that the in situ-generated ¦Á-amino peroxide of tertiary amine and iminium ion act as key intermediates in this oxidative transformation.

In a continuing study of the visible light initiator 5,7-diiodo-3-butoxy-6-fluorone, significant postcure is observed in propylene glycol-maleic anhydride-terephthalic acid-styrene copolymer formed under both aerobic and anaerobic conditions either in the presence or absence of ambient light.
