The peculiarities of chemical bonding and nonlinear optical properties of the complex of Cr(CO) 3 with [2.2]paracyclophane (Cr–pCp) have been studied by a combined experimental–theoretical approach. The Cr–pCp complex exhibits second harmonic generation, the efficiency of which was measured by the powder technique at 1064.2nm fundamental wavelength and estimated theoretically. The comparison...
Nonlinear optical properties of [2.2]paracyclophane (pCp) derived β-diketones containing functional groups with different donor–acceptor properties, bounded to the dicarbonyl fragment, have been studied. Two polymorphic modifications, one of which is characterized by the polar space group Pca2 1 while the other one is centrosymmetric (space group Pbca) were obtained for β-diketone substituted...
