hyperpolarizability values enabled structure–property studies; these revealed some important structural features that affected the efficiency of intramolecular charge-transfer and nonlinearoptical properties in this class ofheterocyclic push–pullchromophores. The charge-transfer transition was most significantly affected by structuralfeatures such as π-linker length, chromophore planarity, and the number

The diamagnetic cobalt(II) complexes [Co-(C4H2N4)2L]2(L = H2O or Me2SO), dimers of bis(diiminosuccinonitrile)cobalt(II), have been synthesized and transformed to the square-planar Co1 complex [Co(C4–H2N4)2]–, and the square-pyramidal Co111 complexes [Co(Me)(C4H2N4)2] and [Co(CN)(C4H2N4)2]; the structure of the latter unusual compound was determined by single-crystal X-ray analysis.

New functionalized cyclophane derivative (DCI-PcP) on the basis of [2.2]paracyclophane and dicyanoimidazole was designed and prepared. Fourier transform infrared spectrometer (FT-IR) suggested triazine and azaporphyrin can be observed in the cured product. DSC showed that DCI-PcP monomer revealed a melting point at 226 °C and exothermic transition at 312 °C. Rheological analysis showed that DCI-PcP
