A series of carbazole based ligands with different lengths were assembled with nickel ions to construct metal-organic macrocycles. High-resolution mass spectrometry and ion mobility-mass spectrometry have been used to analyse the resulting MnLn assembly coexisting in solution. Combining with the structural analysis of their solid confirmation, it was revealed that the diversity of the metal-organic macrocycles was increased with the flexibility of the ligands.

Symmetric-type carbazole derivatives show great potential for application in two-photon absorption (TPA) materials and organic light-emitting diodes. The absorption spectra and fluorescence emission spectra of three different N-alkyl symmetric-type carbazole derivatives were investigated. The density functional theory (DFT) time-dependent-DFT//Becke, three-parameter, Lee-Yang-Parr/6- 31G* method has been used to theoretically study one-photon absorption properties. The computational results are in good agreement with the available experimental values. The two-photon excited fluorescence of the compounds was surveyed by 120fs pulse at 790nm Ti: sapphire laser operating at 1kHz repetition rate. Two-photon excited fluorescence was obtained in the range of 380-600nm, and TPA cross-sections were calculated. The TPA properties of the series of compounds were investigated by the ZINDO/single and double electronic excitation configuration interaction method. The influence of the chemical structure of the compounds on two-photon optical properties was discussed. The results show how the different changes in one-photon absorption and TPA properties on the basis of lengthening the conjugated bridge and the different carbazole N-alkyl substituents are attributed to the transition dipole moment in the excited process.

, (2008/06/13)
A charge transporting material high in solubility in a binder polymer and having high carrier mobility is disclosed, which contains a carbazole derivative represented by the following general formula (1): STR1 wherein Ar1 and Ar2, which may be the same or different, each represents an aryl group which may have a substituent group; R1 and R2, which may be the same or different, each represents a lower alkyl group or an aryl group which may have a substituent group; R3 represents a lower alkyl group, an alicyclic alkyl group having 5 to 7 carbon atoms, an aryl group which may have a substituent group, or an aralkyl group which may have a substituent group; and m and n each represents an integer of 0 or 1. An electrophotographic photoreceptor containing the charge transporting material is also disclosed.
