“…Particularly, the photoinduced piezoelectric and electrostricted quasiphonons may play a crucial role for organic chromophores incorporated within the polymer matrices. 11,12 From this point of view, chromophores possessing transition metals may be of particular interest because they possess relatively localized d states. Among the transition metals, Ru and Cr derivatives may be of particular interest.…”

We have found that Ru derivative chromophores incorporated into the PMMA polymer matrices might be considered as promising materials for optical poling. The maximally achieved effective second-order optical susceptibility for the wavelength 1.89 µm is about 1.94 pm/V. The investigated composites possess metastable trapping levels originating both from the d states of Ru and due to effective charge transfer due to the presence of π-conjugated states. Because of incorporation of the chromophore into polymer matrices, we have revealed that the maximal susceptibility is observed at 5-6% of the chromophore in weighting units. The further increase of the second-order susceptibility is limited by the appearance of chromophore agglomerates substantially restraining second-order susceptibilities. The investigated composites possess long-lived (2) grating, which decreases less than 76% after 600 min of laser treatment. The electrostatic field causes additional reanimation of the second harmonic generation during the decay regime. The electron microscopy pictures clearly confirm appearance of the (2) grating.

“…Due to presence of double bond chain conjugation its have potential application blue emitting fluorescence fluorescent dyes with high florescence quantum yield [4,5] and photonics materials such as optical switching, electrochemical sensing, langmuir films and photoinitiated polymerization [6][7][8]. Therefore quinoline derivatives have widely been used as whitening or brightening reagents for synthetic fibers, for recognition of hole-transport materials in the electroluminescence fields [9,10].…”

Blue emitting cyano substituted isoquinoline dyes were synthesized by one-pot multicomponent reactions (MCRs) of aldehydes, malononitrile, 6-methoxy-1,2,3,4-tetrahydro-naphthalin-1-one and ammonium acetate. Results obtained from spectroscopic (FT-IR, (1)H-NMR, (13)C-NMR, EI-MS) and elemental analysis of synthesized compounds was in good agreement with their chemical structures. UV-vis and fluorescence spectroscopy measurements proved that all compounds are good absorbent and fluorescent. Fluorescence polarity study demonstrated that these compounds were sensitive to the polarity of the microenvironment provided by different solvents. In addition, spectroscopic and physicochemical parameters, including electronic absorption, excitation coefficient, stokes shift, oscillator strength, transition dipole moment and fluorescence quantum yield were investigated in order to explore the analytical potential of synthesized compounds. The anti-bacterial activity of these compounds were first studied in vitro by the disk diffusion assay against two Gram-positive and two Gram-negative bacteria then the minimum inhibitory concentration (MIC) was determined with the reference of standard drug chloramphenicol. The results displayed that compound 3 was better inhibitors of both types of the bacteria (Gram-positive and Gram-negative) than chloramphenicol. Graphical Abstract ᅟ.
