Near-Infrared Fluorescent Probes with Rotatable Polyacetylene Chains for the Detection of Amyloid-β Plaques

The plaques of accumulated β-amyloid (Aβ) in the parenchymal brain are accepted as an important biomarker for the early diagnosis of Alzheimer's disease (AD). Many near-infrared (NIR) probes, which were based on the D-π-A structure and bridged by conjugat

Multipodal arrangement of push-pull chromophores: a fundamental parameter affecting their electronic and optical properties

A series of model push-pull molecules with linear, quadrupolar, and tripodal arrangements, a varyingly substituted amino donor, two acceptors, and a partially extended π-system has been prepared. Two peripheral electron acceptors, namely N,N′-dibutylbarbituric acid and dicyanovinyl, were employed. The fundamental properties of 24 push-pull chromophores were investigated by differential scanning calorimetry, electrochemistry, one-photon absorption spectroscopy, photoinduced piezooptics, and were supported by DFT calculations. Thorough structure-property relationships were elucidated, while a significant influence of the structural arrangement/branching on the electronic and optical properties has been revealed. The fundamental optoelectronic properties of push-pull molecules are affected by their arrangement (linear/quadrupolar/tripodal), the peripheral acceptor attached, extension and planarization of the π-system, and also by the type of auxiliary N-substituent.

N,N′-Dibutylbarbituric acid as an acceptor moiety in push-pull chromophores

Twelve novel D-π-A chromophores with the N,N′-dibutylbarbituric acid acceptor, the N,N-dimethylamino donor and a systematically extended π-linker were synthesized. The extent of intramolecular charge-transfer, structure-property relationships and nonlinear optical properties were further investigated by X-ray analysis, electrochemistry, UV/Vis absorption spectra, calculations and EFISH experiments.

Peralkynylated buta-1,2,3-trienes: Exceptionally low-rotational barriers of camulenic C=C bonds in the range of those of peptide C-N bonds

A variety of 1,1,4,4-tetraal kynylbutatrienes and 1,4-dialkynylbutatrienes was synthezized by dimerization of the corresponding gem-dibromoolefins. Both 1H and 13C NMR spectroscopy indicated that the di- and tetraalkynylated butatrie

In vitro photodynamic properties of chalcogenopyrylium analogues of the thiopyrylium antitumor agent AA1

Several series of chalcogenopyrylium dyes were prepared with one or two 4-anilino substituents at the 2- and 6-positions and with phenyl, 4-N,N-dimethylanilino, or 4-(N-morphilino)phenyl substituents at 2- and/or 4-positions. The dye series are all relate

Selective detection of the carbohydrate-bound state of concanavalin A at the single molecule level

The labeling of molecules with charge-transfer dyes, such as 5-(dimethylamino)-1-napthalenesulfonyl (dansyl) chloride, is a powerful tool for examining the solvent shell of attached substances. This investigation describes the synthesis and application of

Convenient Methods for the Preparation of p-Dialkylaminophenylacetylenes

Two convenient methods for the preparation of p-dialkylaminophenylacetylenes are reported: a) Dehydrobromination of the brominated compounds obtained easily from the dialkylamino substituted cinnamic acids in acetic acid instead of chloroform; b) dehydrochlorination of the 2-chlorostyrene derivative obtained from the reaction of p-dimethylaminobenzaldehyde with chloromethylenetriphenylphosphorane.
