Originální abstrakt

Experimental and quantum mechanical study of the charge carrier mobility photoswitching in poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) doped with the photochromic spiropyran 6-nitro-1',3',3'-trimethylspiro[2H-1-benzopyran-2,2'-indoline] was performed. The photochromic additive undergoes a reversible ring-opening reaction resulting in a significant increase of its dipole moment. Due to charge-dipole interactions, dipolar traps are formed on the polymer chain in the vicinity of dispersed polar species.
