Photophysics of π-conjugated metal–organic oligomers*
The optical absorption and photoluminescence properties of PPE-type π-conjugated oligomers that contain a 2,2-bipyridine-5,5′-diyl metal coordinating unit have been examined. The spectra of the free oligomers are compared with those that contain –Re(CO)3Cl and –Ru(bpy)2 2+ chromophores chelated to the bpy-diyl unit.
متن کاملElectrochemistry and electrogenerated chemiluminescence of π-stacked poly(fluorenemethylene) oligomers. Multiple, interacting electron transfers.
The electrochemistry, spectroscopy, and electrogenerated chemiluminescence (ECL) of a series of π-stacked poly(fluorenemethylene) oligomers (Fn, n = 1-6) were investigated. The pendant cofacially oriented fluorene moieties are essentially in contact with each other by Van der Waals interaction promoting electronic delocalization in these species. All six compounds give successive cyclic voltamm...
متن کاملStructural and Electronic Properties of Novel π-Conjugated Aniline-based Oligomers: A Computational Study
Density functional theory (DFT) and time dependent DFT (TD-DFT) calculations were carried out for the oligomers of 3, 4- Ethylenedioxythiophene –Aniline (EDOT-Ani), 3, 4-Ethylenedithiafurane- Aniline (EDTF-Ani) and Thieno [3,4-b] benzene-Aniline (PITN-Ani). Structural parameters, electrical conductivity, spectral properties and electronic properties like ionization potential (IPs), (EAs), HOMO-...
متن کاملIntrachain electron transfer in conducting oligomers and polymers: the mixed valence approach.
Organic mixed valence compounds consisting of bisdiarylamino charge-bearing units with an oligothiophene bridge and oligothiophene radical cations have been compared using molecular modeling. The study has been performed with oligomers of 1 to 22 thiophene units. These two series of molecules have several properties in common, and intramolecular Single Electron Transfer (SET) in both series can...
متن کاملPolymers Comprising Cholesterol: Synthesis, Self-Assembly, and Applications
This article reviews the current status of self-assembling liquid crystalline polymers comprising cholesterol. This article will focus on synthesis, structure-property relationships and strategies to direct ordering and packing of mesoand nanostructures of cholesterol polymers in the neator melt state and in solution. The applications of these self-assembled structures will be presented.
