Abstract:

Arylated heterocyclic fluorophores are particularly useful scaffolds for numerous applications, such as bioimaging or synthetic photochemistry. While variation of the substitution pattern at the heterocycle and aryl groups allows dye modulation, the bond rotational barriers are also strongly affected. Unsymmetrically substituted ring systems of rotationally restricted arylated heterocycles therefore lead to configurationally stable atropisomeric fluorophores. Herein, we describe these characteristics by determining the properties and configurational stability of atropisomeric, tri-ortho-substi

Abstract:

Due to their high conversion efficiency and low cost of production, dye-sensitized solar cells based on organic dyes have attracted considerable attention. By utilizing various heterocycles as construction blocks for organic dyes, the performance of solar cells was optimized to exhibit good light-harvesting features and suppress interfacial recombinations. The aim of this review is to highlight recent progress in the molecular design of heterocyclic-functionalized organic dyes for efficient dye-sensitized solar cells, and special attention has been paid to the relationship between chemical str

Seven unsymmetrical heptamethine dyes with carboxylic acid functionality were synthesized and characterized.

Abstract:

Chitosan is a valuable, functional, and biodegradable polysaccharide that can be modified to expand its applications. This work aimed to obtain chitosan derivatives with fluorescent properties. Three heterocyclic aromatic dyes (based on benzimidazole, benzoxazole, and benzothiazole) were synthesized and used for the chemical modification of chitosan. Emission spectroscopy revealed the strong fluorescent properties of the obtained chitosan derivatives even at a low N-substitution degree of the dye. The effect of high-energy ultraviolet radiation (UV–C) on modified chitosan samples was studied i

Abstract:

New D-π-D-π-A low-molecular-weight compounds, based on a phenothiazine scaffold linked via an acetylene unit with various donor moiety and cyanoacrylic acid anchoring groups, respectively, were successfully synthesized. The prepared phenothiazine dyes were entirely characterized using nuclear magnetic resonance (NMR) spectroscopy and elemental analysis. The compounds were designed to study the relationship between end-capping donor groups’ structure on their optoelectronic and thermal properties as well as the dye-sensitized solar cells’ performance.

Abstract:

Today, luminescent dyes are widely used in medicine and in various industries. Benzanthrone is widely used as a laser dye, fluorescent pigment,as well as various medical examinations, for example, antibodies are labeled with luminescent dyes to detect antigens in cells. Work aim is synthesize new luminescent benzantrone derivatives with benzimidazole and amino acid residues. Reaction ability of 3-N-(2-chloro-acetamido)benzanthrone to replace the chlorine atom with various heterocyclic amines and amino acids was investigated.

Abstract:

We demonstrate that the performances of dye-sensitized solar cells (DSCs) sensitized with a previously reported N-heterocyclic carbene iron(II) dye in the presence of chenodeoxycholic acid co-adsorbant, can be considerably improved by altering the composition of the electrolyte while retaining an I−/I3 − redox shuttle. Critical factors are the solvent, presence of ionic liquid, and the use of the additives 1-methylbenzimidazole (MBI) and 4-tert-butylpyridine (TBP). For the electrolyte solvent, 3-methoxypropionitrile (MPN) is preferable to acetonitrile, leading to a higher short-circuit current
