[reaction: see text] A series of electron-transfer chromophores containing a donor and acceptor linked by an alkyl spacer were synthesized, and their electronic spectra were investigated. By inclusion with amylose, the supramolecularly encapsulated c

We recently found that certain cyanines form tight complexes with carboxymethylamylose (CMA) in aqueous solutions and that in these complexes the cyanine exists as a strongly fluorescent and stable J-aggregate. Cyanine dyes are characterized by their

The J-aggregation of Cyanine-1dye in the presence of carboxymethyl amylose (CMA) is described. The J-aggregation requires a large excess CMA concentration; the J-band maximum appears in the concentration range, [CMA]/[dye] = 10-50, depending on the d

A white light emission was observed from a single-layer emitting system consisting of an equimolar blend of two blue emitters of a bipolar oligomer, 9,9-spirobifluorene-centered bioxadiazole (303) and polyvinylcarbazole (PVK), featuring a single broa

In this paper, we study three symmetrical D-pi-D chromophores containing dithieno[3,2-b:2',3'-d]thiophene (DTT) as the pi-center and various donor end moieties, by means of UV-vis-NIR and FT-Raman spectroscopy and in situ spectroelectrochemistry. The

Several different series of conjugated oligomers bearing various π-centers such as dithienothiophene (DTT), fluorene and terthiophene moieties, attaching electron donor and/or electron acceptor units through conjugation were synthesized and assessed

A series of D/D- and D/A pair conjugated chromophores based on dithienothiophene, DTT, as conjugated linker (π-center) were synthesized (D-π-D and D-π-A) and studied optical and electrochemical properties. Unusual bipolar behavior was observed wit

A technique has been established to determine the first hyperpolarizability value β of fluorescent molecules based on femtosecond hyper-Rayleigh scattering (HRS). The intrinsic high harmonic content of the femtosecond pulse train is used as a high f

Hemicyanine dye structure is modified with a C 16 -alkyl chain to amino-head and a C 1 , C, or C 16 alkyl to pyridinium-tail. Spectral properties of the dyes in supramolecular inclusion complexation with amylose are studied in order to assess the mon
