Surface Chemistry and Catalysis

Metal-free phthalocyanines and metal phthalocyaninates (M = Ni, Cu, Co or Zn) carrying eight alkylthio-groups on peripheral positions have been synthesised from 4,5-bis(alkylthio)phthalonitrile and 1,8-diazabicyclo[5.4.0]undec-7-ene (dbu) or the corresponding anhydrous metal salt [NiCl2, CuCl, CoCl2 or Zn(O2CMe)2]. Th…

The chirality of nanoparticles (NPs) and their assemblies has been investigated predominantly for noble metals and II–VI semiconductors. However, ceramic NPs represent the majority of nanoscale materials in nature. The robustness and other innate properties of ceramics offer technological opportunities in catalysis, b…

Considerable interest in calcite crystallization has prompted many studies on organic molecule adsorption. However, each study has explored only a few compounds, using different methods and conditions, so it is difficult to combine the results into a general model that describes the fundamental mechanisms. Our goal wa…

We combine scanning tunneling microscopy (STM) measurements with ab initio calculations to study the self-assembly of long chain alkanes and related alcohol and carboxylic acid molecules on graphite. For each system, we identify the optimum adsorption geometry and explain the energetic origin of the domain formation o…

Pyrrole (C 4 H 5 N) was embedded in low-temperature solid inert matrixes (argon, xenon; T = 9 K) and both the monomer and low-order aggregates characterized by FTIR spectroscopy. The spectroscopic studies were complemented by extensive theoretical [DFT(B3LYP)/6-311++G(d,p)] structural and vibrational studies carried o…

The use of calixarenes in asymmetric catalysis is receiving increasing attention due to their tunable three-dimensional molecular platforms along with their easy syntheses and versatile modification at the upper and lower rims. This review summarizes the recent progress of synthesis and use of chiral calixarenes in as…
