All-round performance: a donor–?–acceptor type push–pull arylene–vinylene conjugated terpyridine showing multifunctional properties of solvatochromism, vapochromism, piezofluorochromism and remarkable fluorescence sensing properties.

In this paper we present a synthetic approach to six new D-π-A-D conjugated chromophores containing the N-[ω-(4-methoxyphenoxy)alkyl]carbazole fragment. Such readily functionalizable heterocycle as carbazole was used as a main starting compound for their preparation. The investigation of the optical properties has shown that the positive solvatochromism is inherent to the chromophores containin...

Photoacidity is frequently found in aromatic alcohols where the equilibrium dissociation constant increases by some orders of magnitude upon electronic excitation. In this study we investigated the solvatochromism of a family of recently synthesized super-photoacids and their methylated counterparts based on pyrene. The chemical similarity of these molecules on the one hand and their differing ...

A series of chromophores was designed and synthesized using 2-(3-cyano-4,5,5-trimethylfuran-2 (5H) -ylidene) malononitrile (TCF) as the electron acceptor differing from each other by use thirteen different donors. The dyes were characterized for their optical electrochemical properties theoretical calculations also carried out to support experimental results. By changing donor in dyes, absorbin...

For two free base corroles with different architecture of peripheral substitution, the solvatochromic shifts absorption bands in a series solvents nature are herein determined, and effects is analyzed by Valentine method. It found that solvatochromism bases originates due to universal nonspecific interactions, short-wavelength T2 tautomer experiences stronger solvation. shown polar aprotic (ace...

A newly synthesized 8-quinolinol platinum(II) chelate derivative gelates various organic solvents, and the gel formed shows unique thermo- and solvatochromism of visible and phosphorescent colour in response to a sol-gel phase transition and possesses an attractive ability to inhibit dioxygen quenching of excited triplet states.

Reversible mechanochromic luminescence (ML) is known for difluoroboron β-diketonates (BF2bdks). Here, we report ML for the methoxy-substituted dinaphthoylmethane (dnmOMe) ligand even without coordination to boron. In addition, dnmOMe shows solvatochromism and aggregation-induced emission (AIE). Diketone thin films showed high contrast emission when smeared, and rapid recovery of the pre-smeared...

The spectral properties of several azulene-oxazolone derivatives containing a phenyloxazolone moiety linked to substituted azulene ring via C=C double bond were studied in different solvents varying polarity. solvatochromism and the ability recognize heavy metal ions investigated. In order estimate contribution non-specific specific solute–solvent interactions, multiple linear regression analys...
