, p. 5421 - 5423 (2005)
A new and cheap protocol for controlled iodination in the para-position of various aniline derivatives is presented. It operates under mild conditions by reacting the aniline derivatives with molecular iodine in a mixture of pyridine/dioxane (1/1 vol) at 0°C.

A series of photocrosslinkable polymers bearing hyperpolarizable side chain chromophores was synthesized, poled and evaluated on the basis of the thermal stability of Second Harmonic Generation (SHG). Photoinitiation allowed for control of the onset of curing. Crosslinking was monitored by infrared spectroscopy and optimal conversion was achieved by applying a slow temperature ramp during exposure. The ultimate stability of the poled polymers was directly related to the number of crosslinking substituents that were attached to the chromophore pendant group. With two reactive groups per chromophore significant SHG was retained at temperatures above the initial polymer glass transition temperature.

The glass transition temperature of the novel compound, poly(2,5-dipropargyloxybenzoate) containing a polar aromatic diacetylene was 105 °C and differential scanning calorimetry showed two exothermic peaks due to the opening of the hexa-2,4-diynylene-1,6-
Synthesis of hydroxyalkyl-substituted, push-pull chromophores based on diphenylacetylenes and 1,4-bis(phenylethynyl)benzenes
Cross, Tara A.,Davis, Matthew C.
, p. 499 - 516 (2008/04/12)
Six new push-pull chromophores based on phenylacetylenes were prepared: two 1,2-diphenylacetylenes and four 1,4-bis(phenylethynyl)benzenes. The donor amino groups have hydroxyethyl substituents, and the acceptor groups are cyano or nitro. More soluble ver

Monnereau, Cyrille,Blart, Errol,Montembault, Véronique,Fontaine, Laurent,Odobel, Fabrice
, p. 10113 - 10121 (2007/10/03)
In this paper, the synthesis of a crosslinkable co-polymer containing new push-pull arylethynyl zinc porphyrins is described. The synthesis of porphyrin chromophores, analogous to Therien's porphyrin (J. Am. Chem. Soc. 1996, 118, 1497-1503) functionalized
Ablatively photodecomposable compositions

, (2008/06/13)
The present invention provides an ablatively photodecomposable polymer having a photoabsorber bound to the polymer (the "ablatively photodecomposable polymer") which does not phase separate, nor does it crystallize. The ablatively photodecomposable polyme
