measurements, and further supported by theoretical calculations (DFT, TDDFT). The pH‐sensing properties of the TPyzPzs have been investigated in THF and in water after anchoring the TPyzPzs to liposomes. The salient pKa values were around 1.3 (azomethine nitrogen) and 2.29–4.76 (donor for ICT). The lead indicators (sensing over a pH range of 1.0–2.5) with fairly steep sensing profiles exhibited increases in

A series of novel X-shaped pushâpull compounds based on benzene-1,2-dicarbonitrile has been designed, synthesized and further investigated by X-ray analysis, electrochemistry, absorption and emission spectra, SHG experiment and quantum-chemical calculations. The obtained data were compared with those for isolobal 5,6-disubstituted pyrazine-2,3-dicarbonitriles. Structureâproperty relationships were elucidated. The extension, composition and planarization of the Ï-linker used as well as the electron-withdrawing ability of both dicyano-substituted acceptor units affect the linear and nonlinear properties of the target charge-transfer chromophores most significantly.
donor-substituted phenyleneethynylene molecules with up to three 1,4-phenylene and two acetylenic units were synthesized by Suzuki–Miyaura and Sonogashira cross-coupling reactions and further studied by absorption and emission spectra and theoretical calculations. The π-system between the N,N-dimethylamino group and terminalacetylene was systematically elongated which allowed elucidation of the fundamental structure–property
