We review activity on the usage of a biphase H2O/CO2 system in organic synthesis as reaction medium green chemistry. The formation self-neutralizing carbonic acid such eliminates problem salt disposal, typical for acid-catalyzed reactions with usual mineral and acids. A large variety different to be performed are discussed detail, including cyclization/cycloaddition, hydroformylation, hydrogenation, reduction, coupling, rearrangement, substitution, addition, halogenation, hydrolysis,...
In this communication, the results of theoretical investigations a 1,3,5,7-tetramethyl-BODIPY derivative (TMB) and dimeric molecule composed two TMB fluorophores linked by flexible siloxane spacer (di-TMB) in various solvents are presented. The existence energetically close configurations for di-TMB is revealed. analysis patterns frontier molecular orbitals indicates that highest occupied orbital (HOMO) lowest unoccupied (LUMO) predominantly localized on chromophores. Furthermore, molecule,...
Two approaches to the selective synthesis of polyfunctional stereoregular cyclosiloxanes from polyhedral organometallasiloxanes are reported.The molecules possess sandwich or globular structure and contain one two organocyclosiloxanolate fragments coordinated metal ions.According first approach were prepared primarily then treated with chlorodimethylsilane dimethylchlorovinylsilane. The second method is based on initial transforming into cyclic polysiloxanols reacted afterwards corresponding...
Nowadays, luminescent materials attract wide attention due to their valuable characteristics and broad area of potential application. Luminescent silicone-based polymers possess unique properties, such as flexibility, hydrophobicity, thermal chemical stabilities, etc., which allow them be utilized in various fields, optoelectronics, solid-state lasers, solar concentrators, sensors, others. In the present work, a metal-ligand interaction approach was applied obtain new cross-linked based on...
Abstract Fluorescent dyes which exhibit emission/excitation in the second near‐infrared (NIR‐II, 1000–1350 nm) region are currently attracting significant attention bioimaging and diagnostics applications. Furthermore, with high two‐photon absorption cross‐section (TPA), such as BODIPY derivatives, of a particular interest due to deeper signal penetration into biological tissues, better image contrast, reduced phototoxicity photobleaching. Herein we report synthesis properties new monomeric...
The optical properties of aluminum hole arrays fabricated via colloidal lithography were investigated. By tuning the diameter and spacing independently, their influence on Bloch wave–surface plasmon polariton (BW-SPP) localized surface resonances (LSPR) could be identified. used to enhance fluorescence a dibenzoylmethanatoboron difluoride (DBMBF2) dye. dye exhibits advantageous property forming an exciplex with aromatic compounds. interaction DBMBF2 monomer DBMBF2–toluene exciplexes Al is...
A simple fluorescent sensor utilizing a material based on dibenzoylmethanatoboron difluoride (DBMBF2) fluorophore capable of forming exciplexes with benzene, toluene and xylenes (BTX) has been developed. physicochemical model for the dependence sample emission spectra exposure to vapors aromatic compounds was used formulate criteria which should be fulfilled detect individual analytes in multicomponent mixture. It is experimentally demonstrated that after calibration provides simultaneous...
Abstract A series of methoxylated bis(pentafluorophenyl)boron‐ β ‐diketonates (dkB(C 6 F 5 ) 2 with intense emission has been synthesized and characterized by a variety physicochemical methods. The photophysical properties the compounds were thoroughly investigated electronic absorption, steady‐state, time‐resolved fluorescence spectroscopy in both solution solid state. studied exhibit solvatochromic behavior attributed to intramolecular charge transfer (ICT) nature first excited formation...
Alkoxysilyl derivatives of dibenzoylmethanatoboron difluoride (DBMBF2) are synthesized by the hydrosilylation reaction corresponding O-allyl DBMBF2 with triethoxysilane. The photophysical properties and alkoxysilyl investigated. It is found that absorption fluorescence spectra essentially depend on position or O-propyl substituent. highest quantum yield obtained for para-position, whereas substitution at meta-position gives largest bathochromic shift in spectrum. Density functional theory...
