“…A well-known example of such a push-pull conjugated system is trans 4-dimethylamino-4Ј-nitrostilbene (DANS), [4] a member of the trans 4,4Ј-disubstituted stilbene family (Scheme 1), which has been studied predominantly for its special photophysical and NLO properties. [5][6][7][8] Currently, conjugated systems containing transition metals attract much attention, [9][10][11][12][13] especially because the optoelectronic properties of these systems can be affected by changing the metal ion, the coordinating anions and ligands or by changing the nature of the connecting conjugated system.…”

A series of novel 4,4Ј-disubstituted organic-organometallic stilbenes were synthesized, that is, the 4Ј-substituted stil--in which R = C 2 H 2 C 6 H 4 -RЈ-4Ј with RЈ = NMe 2 , OMe, SiMe 3 , H, I, CN, NO 2 ) (1-7). In these compounds the PtCl grouping can be considered to be present as a donor substituent. Their synthesis involved a Horner-Wadsworth-Emmons reaction of [PtCl(NCN-CHO-4)] (9) with the appropriate phosphonate ester derivatives (8a-g). Under these reaction conditions, the C-Pt bond in aldehyde 9 was not affected, and the platinated stilbene products were obtained in 53-90 % yield. The solidstate structures of complexes 1, 2 and 5-7 were determined by single-crystal X-ray diffraction, which revealed interesting bent conformations for 2, 5 and 7. Linear correlations were found between both the 13 C{ 1 H} (C ipso to Pt) and the

“…Compounds 1 -12, possessing heteroaromatic moieties with different electron donating abilities linked by a vinyl to the strong electron withdrawing pyridinium ring, belong to the class of the so called push-pull (donor-acceptor, D-A) molecules. Such push-pull conjugated systems are possible candidate components of non linear optics, which are already well documented for push-pull ethenes for example 4-dimethylamino-4'-nitrostilbene (DANS) 4 and for heterocyclic…”

The synthesis and spectroscopic characterization of trans 1-heteroaryl-2-(1-methylpyridinium-2-yl) ethylene iodides is reported. The 5-(4-bromophenyl)furan derivative exhibited the highest in vitro antitumor activity against MCF7 (breast) and LNCap (prostate) carcinoma cells. Solvatochromic and NMR shifts provided evidence for modulation of electronic parameters which could be used to optimize frequency emission and conversion efficiency in such push-pull conjugated systems, which are potential components of non linear optics materials.

“…Bei der Verlängerung der p-Brücke in D-OP-A-Systemen kann sich eine Erhöhung der b-Werte ergeben; [71,111,112] ähn-lich wie bei l max (n) ist allerdings auch der Gang durch ein Maximum von b(n) möglich. Der erste Fall tritt bei 56 a-c (D = OCH 3 /A = NO 2 ) auf, der zweite bei 55 a-d (D = NH 2 / A = NO 2 ).…”

Konjugierte Oligomere sind in theoretischer, präparativer und materialwissenschaftlicher Hinsicht eine prominente Substanzklasse. Die Push‐pull‐Substitution durch einen Elektronendonor an einem Ende und einen Elektronenacceptor am anderen Ende verleiht den Verbindungen D‐π‐A besondere optische und elektronische Eigenschaften. Der vorliegende Aufsatz schildert die grundsätzlichen Strategien zur Synthese solcher Oligomerenreihen mit n Wiederholungseinheiten (n=1, 2, 3, 4, …︁) und die für ihre linearen und nichtlinearen optischen Eigenschaften (Absorption, Frequenzverdoppelung und ‐verdreifachung) geltenden Gesetzmäßigkeiten. Aus den chemischen, physikalischen und theoretischen Aspekten der push‐pull‐substituierten konjugierten Oligomere soll sich ein interdisziplinäres Bild dieser Verbindungsklasse zusammenfügen.
