Triplet Energy Transfer in Bichromophoric Amino Acids, Dipeptides and Carboxylic Acid Diesters
Original language description
The Intramolecular Triplet-triplet Energy Transfer (ITET) in various bichromophoric amino acids (glycine, valine, phenylalanine, and sarcosine), dipeptides (diglycine, diphenylalanine), and a simple diester, with the benzoyl and naphthyl terminal groupsserving as donor and acceptor, respectively (Fig. 1), were studied by the steady-state photokinetic measurements. The efficiency of a through-space exothermic ITET was affected by the interchromophore distance (8 or 11 atoms), the nature of the connectinng chain as well as the side chains. Rigidity of the peptide bond in short bichromophoric compounds causes that the ITET processes are controlled by ground-state conformational distribution. Whereas a less rigid diester would allow that certain unfavorable conformations may coil to favorable ones within an excited-state lifetime (< 10-8 s). Flexibility of the bichromophore with ester moiety and the steric effect of the side hydrocarbon groups in valine- and sarcosine-based molecules lead

Přenos tripletové energie u bichromoforů aminokyselin, dipeptidů a diesterů karboxylových kyselin
Czech description
Intramolekulární přenos triplet-tripletové energie (ITET) byl uskutečněn u bichromoforů aminokyselin (glycin, valin, fenylalanin a sarkosin), dipeptidů (diglycin, difenylalanin) a jednoduchém diesteru kys. octové. Benzoyl and naftylové skupiny na konci molekul sloužily jako donor, resp. akceptor tripletové energie. ITET u těchto bichromoforů byl studován pomocí steady-state fotokinetických měření.
