چکیده

The photodegradation properties of six electro-optic chromophores in guest-host polymer formats were measured as a function of wavelength throughout the visible and up to 1.3 ␮m in the near infrared. The chromophore structure was varied to provide insight into its relationship with photostability.

Systematic behavior of electro-optic chromophore photostability.

The wavelength dependence of the one-photon absorption-induced photodegradation rate has been measured from the visible to the near IR for a variety of electro-optic chromophore-doped polymers. Systematic behavior is identified. The lifetime of the electro-optic activity is found to increase exponentially over 4-6 orders of magnitude for wavelengths ranging from peak of absorption, typically in...

The synthesis of new double-donor chromophores with excellent electro-optic activity by introducing modified bridges.

A series of chromophores y1–y3 based on the same bis(N,N-diethyl)aniline donor and the tricyanofuran acceptor (TCF) linked together via the modified thiophene π-conjugation with different isolated groups have been synthesized and systematically investigated in this paper. Density functional theory (DFT) was used to calculate the HOMO–LUMO energy gaps and first-order hyperpolarizability (β) of t...

Functional phosphorus-based -conjugated systems: Structural diversity without multistep synthesis*

The synthesis and properties of linear π-conjugated systems incorporating phosphole rings are described. Their supramolecular organization in the solid state can be controlled either by chemical modifications or coordination to transition metals of the phosphorus atom. Furthermore, chemical transformations of the phosphole ring allow organizing these P-chromophores in 3D assemblies exhibiting σ...

Supramolecular Assemblies of Cucurbiturils with Photoactive, π‐conjugated Chromophores

Supramolecular assemblies of cucurbituril (CBn) homologues with p-conjugated chromophores will be overviewed. Special emphasis will be given to the effect of CBn on the optical properties of conjugated oligomers and polymers. How supramolecular complexes of p-conjugated chromophores including porphyrin derivatives, conjugated oligomers and polymers with CBn could be utilized in the theranostic ...
