We calculate the next-to-leading order （nlo） quantum chromodynamics （QCD） corrections to double charmonium production processes e^＋e^- → γ＊ →ηc＋hc（1P）/ψ1,2（1D） within the non-relativistic QCD （NRQCD） factorization framework. We find that the corrections to ηc＋hc（1P） production are positive, while those to ηc＋ψ1/2（1D） are negative. Unlike the J/ψ＋ηc case, all the corrections here are not large. Uncertainties in the renormalization scale, quark mass and running energy of center-of-mass are discussed, and the scale dependence of these processes is found to be greatly reduced with the nlo QCD corrections.

A series of new stable (thermal and photochemical) ferrocenyl derivatives containing C=N bond and benzene ring in long conjugated chains have been synthesized and characterized by (HNMR)-H-1(400MHz), IR, and elemental analysis. Pull-push ferrocenyl complexes that we have prepared have strong nlo responses identified by electronic absorption spectrum.

Nonlinear optical single crystals of L-phenylalanine-4-nitrophenol have been grown by the slow evaporation method. The grown crystal was subjected to the single crystal X-ray diffraction analysis, to confirm that it belongs to the monoclinic crystal structure, with space group P21. The optical transmission study reveals the transparency of the crystal in the entire visible region and the cut off wave length has been found to be 320 nm. The optical band gap is found to be 3.87 eV. The transmittance of the L-phenylalanine-4-nitrophenol crystal has been used to calculate the refractive index (n), the extinction coefficient (K) and the real (εr) and imaginary (εi) components of the dielectric constant. The mechanical behaviour of the grown crystals was studied using Vicker’s microhardness tester. The dielectric constant and dielectric loss of L-phenylalanine-4-nitrophenol are measured in the frequency range of 50 Hz to 5 MHz at different temperatures. The photoconductivity study confirms the negative photoconductive nature of the sample.

To explore the relationship between the intra-and inter-molecular charge transfer and nonlinear optical property,two molecules(2 and 2)are designed by boron/nitrogen atoms substituted the central carbon atom of the phenalenyl moieties in s-indaceno[1,2,3-cd;5,6,7-c’d’]***,the first hyperpolarizability(β=4.56×10 au) of 2 with intra-molecular charge transfer greatly larger than that of reported molecule 3(5.45×10 au) with inter-molecular charge transfer.2 exhibit the largest β value to be 1.42×10 au due to the combination of intraand inter-molecular charge *** was surprised to find that the main contributions to the β value are β(1.40×10 au) and β(2.27×10 au),which may be caused by the intra-and inter-molecular charge transfer transition,*** believe that present work provide rich insight into the design of novel inter-and intra-molecular charge transfer materials for experimentalists and theoreticians to develop the potential nlo materials on the basis of dimers.
