聚碳酸酯薄膜中苝与碘之间的非共价（电荷转移）相互作用使含有溶解苝的聚合物薄膜暴露于溶剂+碘蒸气时，在聚合物表面形成微结构的苝层。所制备的双层膜对碘蒸气具有传感作用，其荧光和电导率变化均可观察到。以蒽和吩噻嗪为π给体，采用不同的聚合物基质制备了类似的双层膜。通过M06-2x DFT计算，研究了碘与多环芳烃（PAH）的相互作用，从而更好地理解聚合物膜表面π给体的微结构现象。
Noncovalent (charge transfer) interaction between perylene and iodine in polycarbonate film provides formation of microstructured perylene layer on the polymer surface upon exposure of polymer film which contains dissolved perylene to solvent + iodine vapors. The prepared bilayer film possesses a sensing effect to iodine vapors which can be observed by both fluorescence and electrical conductivity changes. Similar bilayer films have been prepared also with anthracene and phenothiazine as π-donors with use of different polymer matrixes. Interaction of iodine with polycyclic aromatic hydrocarbons (PAH) has also been studied by the M06-2x DFT calculations for better understanding of phenomenon of π-donors microstructuring on surface of polymer film.
