Influence of an electron-acceptor substituent type on the photophysical properties of unsymmetrically substituted diphenylacetylene
Szyszkowska, Ma?gorzata,Bylińska, Irena,Wiczk, Wies?aw
, p. 76 - 88 (2016)
Unsymmetrically substituted diphenylacetylene derivatives containing a different type of an electron-acceptor substituent were synthetized and studied using spectroscopic methods in order to establish the influence of electron affinity of substituent on t
The [2 + 2] Cycloaddition-Retroelectrocyclization and [4 + 2] Hetero-Diels-Alder Reactions of 2-(Dicyanomethylene)indan-1,3-dione with Electron-Rich Alkynes: Influence of Lewis Acids on Reactivity

The reaction of electrophilic 2-(dicyanomethylene)indan-1,3-dione (DCID) with substituted, electron-rich alkynes provides two classes of push-pull chromophores with interesting optoelectronic properties. The formal [2 + 2] cycloaddition-retroelectrocycliz
Synthesis and non-linear properties of disubstituted diphenylacetylene and related compounds
Kondo, Koichi,Fujitani, Takumi,Ohnishi, Noriaki
, p. 429 - 433 (2007/10/03)
A variety of disubstituted diphenylacetylenes and related compounds have been synthesized by a modified Horner-Emmons reaction, and their second harmonic generation (SHG) has been evaluated by the Kurtz powder method. The diphenylacetylenes with weak electron-donating and -withdrawing groups are found to be efficient for SHG, as well as having the lowest cut-off wavelength.
The electronic structure and second-order nonlinear optical properties of donor-acceptor acetylenes: A detailed investigation of structure-property relationships
Stiegman,Graham, Eva,Perry, Kelly J.,Khundkar, Lutfur R.,Cheng,Perry, Joseph W.
, p. 7658 - 7666 (2007/10/02)
A series of donor-acceptor acetylene compounds was synthesized in which systematic in both the conjugation length and the donor-acceptor strength were made. The effect of these structural changes on the spectrcscopic electronic proprties of the molecules
