Název v původním jazyce

A Molecular Photosensor Based on Photoswitching of Charge Carrier Mobility

Popis výsledku v původním jazyce

Polymer photoelectronic device based on interaction between ?-conjugated polymer matrices and photochromic molecules was fabricated. The theoretical and experimental studies proved that the photochromic reaction in studied devices should eventuate in changes of optical and electrical properties of polymers such as luminescence and conductivity. The quantum chemical calculations showed that the presence of dipolar species in the vicinity of a polymer chain modifies the on-chain site energies and consequently increases the width of the distribution of hopping transport states. Optical switching was studied using standard absorption and photoluminescence spectroscopy. A strong photoluminescence quenching after the photochromic conversion caused by radiative energy transfer was observed. The influence of photoswitchable charge carrier traps on charge transport were evaluated by Space Charge Limited Current (SCLC) method. It was shown that deep traps may significantly affect the energy of t
