Transparent PDMS films of zeolites incorporating organic guests: quantitative determination of photophysical parameters by transmission techniques
Article Abstract:
Photophysical parameters of zeolites may be quantitatively determined from a transparent film of zeolite crystals. The film may be prepared by dispersion of the zeolite particles containing organic cations in poly(dimethylsiloxane) polymer. Quantitative transmission techniques may be used to monitor the transient species generated upon laser flash photolysis. These photophysical parameters of a guest molecule hosted in a zeolite can be very similar to the values in solution.

Organic crystal fibers aligned into oriented bundles with polarized emission
Article Abstract:
A simple method for growing organic crystal fiber bundles as long as centimeters by controlling the shape and dimension of the evaporation channel of the chloroform solution of N,N'-bis(1-ethylpropyl)-3,4,9,10-perylenebis(dicarboximide) (EPPTC) is presented. Results reveal distinct stacking of the molecules in the crystal fibers with very good alignment.

Mixed valence compounds as probes to determine the polarity of 1-butyl-3-methylimadazolium ionic liquids
Article Abstract:
The mixed valence compounds are applied to determine the polarity of 1-butyl-3-methylimadazolium ionic liquids is discussed. The results indicate that the ionic liquids are not exceptional liquids in terms of polarity.
