Chiral templating of polycarbonate membranes by pinene using the modified atomic layer deposition approach

Popis výsledku v původním jazyce

In this article, chiral templating of a polycarbonate (PC) membrane by (−)-α-pinene using the atomic layer deposition (ALD) approach is investigated. The templating with the enantiomer of (−)-α-pinene, used as a case compound, was performed either on the original commercial PC membrane or on the PC membrane with a beforehand deposited Al2O3 layer. The efficiency of the templating was assessed by a difference in the membrane ability to adsorb/absorb (−)-α-pinene, (+)-α-pinene, and their racemic mixture, using a very sensitive gas sorption analyzer. The results clearly show that the solution-diffusion mechanism rather than the sieving mechanism applied for adsorption/absorption of (−/+)-α-pinene enantiomers, which have the same size of the molecule. The PC membrane with the predeposited Al2O3 before the (−)-α-pinene templating shows significantly higher sorption of (−)-α-pinene compared to (+)-α-pinene and racemate, which clearly demonstrates the presence of a chiral recognition effect.
