  abstract = 	{In this Thesis, the effect of structural modifications on the ultrafast dynamics and photochemical properties of furylfulgides and azobenzenes, as two important classes of photochromic switches, was investigated by femtosecond time-resolved transient absorption spectroscopy (fsTAS). The parent compound of the furylfulgides (MeF) was systematically modified by steric and electronic effects with a bulky isopropyl substituent (iPrF) or by intramolecular bridging (7rF) at the hexatriene/cyclohexadiene chromophore and by benzannulation of the furyl ring (MeBF), respectively. The second task was the investigation of the photo-induced isomerization of a highly constrained bridged azobenzene derivative (brAB), which can be regarded as a new improved class of azobenzenes.},
