It came through the period with its old regime institutions intact, having missed out on the ...
Properly designed organic molecules where a -conjugated bridge is end-capped by an electron-donor and electron-withdrawing group (push-pull chromophores) can show, under specific conditions, frequency-upconverted lasing emission. Materials based on these dyes are therefore able to convert the emission ...
Dicyanoisophorone derivatives (1–3), which contain a strong push–pull chromophores system, have been prepared by a two-step condensation reaction, and their fluorescence in solution, polymeric thin film and pure solid state are measured. It is found that 1–3 exhibit no or weak fluorescence ...

H2TPP(CH3)2(X) where X = NO2 and CHO exhibited very high dipole moment values (5.76‐7.59 D) as compared to H2TPP (0.052 D) due to push‐pull effect. These push‐pull porphyrins exhibited lower HOMO‐LUMO gap as compared to MTPP(NO2) and MTPP. The redox tunability was achieved ...

These push–pull molecules represent a first systematic modification of an indan-1,3-dione-fused benzene ring. The structures and properties of all target molecules were investigated by X-ray analysis, electrochemistry, UV/Vis absorption spectroscopy, differential scanning calorimetry, electric-field-...
