      Polysulfone (PSF) and sulfonated polysulfone (SPSF) were synthesized and characterized by IR spectra. The performances in ammonia synthesis were investigated and compared at atmospheric pressure and low temperature (25–100°C) using Nafion and SPSF membranes. The results demonstrated that the proton conducting performances of Nafion and SPSF membranes were similar and the rates of evolution of ammonia are almost the same for both of them.

The La/SiO2 catalysts were characterized by AES, BET, XRD, TEM, FT-IR, XPS and TPD, and the characterization results showed that LaOOH was the possible active species and high surface area was important for the high catalytic activity. By applying the optimized reaction conditions, various carbamates with up to 90% isolated yield were synthesized.

      A pair of chromophores with donor-acceptor properties, 3-CCA and 9-ACA, were successfully intercalated into Zn-Al-LDH compounds by a method of ion-exchange procedures in ethylene glycol. The results show the existence of guest-host interaction, guest-guest interaction and guest-guest energy transfer in the co-intercalation compounds. The co-intercalation compounds could be developed for a novel class of layered light energy storage and conversion materials.

      The aromatic rings in the spacer of light-sensitive Gemini surfactants MCm(azo)MCm adopt an orientation parallel or near-parallel to the air/water interface in the Langmuir monolayer no matter whether they are irradiated. This is believed to be due to the absence of ionic groups in the headgroup-region.

      Star-shaped molecules that comprise a 1,3,5-trisub- stitued benzene core and three oligoaryleneethynylene arms show great potential for application in organic light-emitting devices (OLEDs). Their optical and electronic properties are tuned by the star-shaped molecular size, namely, the number of dimethoxyphenyleneethynylene units and the number of the methoxy groups on the terminal benzene rings at each arm. To reveal the relationship between the properties and structures, we apply quantum-chemical techniques to investigate these organic star-shaped molecules.
