1. 1. Probing the Effects of Conformation on the Photophysics of Conjugated Porphyrin Oligomers

   Författare :Melina Gilbert Gatty; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron transfer; conformational analysis; conjugated porphyrin oligomers;

   Sammanfattning : Controlling the conformational heterogeneity of molecular systems is fundamental to envisage future applications of these systems, such as in solar cells or molecular devices to name a few. The work presented in this Thesis investigates the effects of conformational flexibility on the photophysical properties of a series of conjugated porphyrin oligomers Pn (n = 1-4, 6, 8). LÄS MER
