Die Umsetzung von CaC2 zu einem modularen C2‐Baustein ermöglicht die Synthese eines α,ω‐Bis(vinylthio)‐Monomers sowie dessen Weiterumsetzung zu kristallinen, sequenzdefinierten, schwefelfunktionalisierten Polymere. Dichte Thioether‐Cluster induzieren nichtkonventionelle Lumineszenz und ermöglichen eine präzise Kontrolle der Struktur‐Eigenschafts ...

Many of the pigments that are widely found in coloured parts of mollusc shells are polyenes, i.e. molecules with a central polyenic chain (carbon-carbon single and double bonds).

Plasma Oscillations in Large Ring Polyenes
The possibility of collective motion of the :n:-electron system has been examined by many authors1- 3• In this context it is interesting to note that much more attention has been devoted to the linear conjugated systems than to the ring ones.

Effect of charge and spin multiplicity on hyperpolarizabilities of donor-acceptor substituted polyenes [PDF]
756-766Theoretical studies of the ground state structure and nonlinear optical (NLO) properties of a number of donor-acceptor substituted singlet and triplet (neutral) and doublet (mono-positive and mono-negative) polyenes have been carried out.

Excited State Potential Energy Surfaces of Polyenes and Protonated Schiff Bases
The potential energy surface of the 1Bu and 1A′ states of all-trans-polyenes and the corresponding protonated Schiff bases have been studied at density functional theory and coupled cluster levels. Linear polyenes and protonated Schiff bases with 4 to 12

Nonlinear Optical Properties of Polyenes: Electron Correlation and Chain Conformation
Using a recently developed many-electron theory of second and third order nonlinear optical susceptibilities, microscopic descriptions of γxxxx(-3ω;ω,ω,ω) are presented for two conformations of polyenes.

Optical nonlinearities in polyenes: role of intrinsic localized modes
Within a simple theoretical model we demonstrate analytically the effect of intrinsic localized modes such as breathers on nonlinear optical properties. We have earlier observed enhancement of optical nonlinearities in ab initio numerical simulations of ...

Nonlinear polarizabilities of donor-acceptor substituted conjugated polyenes
The polarizabilities of conjugated polyenes with 8-36 carbon atoms are calculated using the time dependent Hartree-Fock (TDHF) technique. By examining the reduced single-electron density matrix, we explore the relations among the ground state chemical ...
