## Abstract Oligosarcosines, which contain as azobenzene group at the center of the chain and amino groups at both ends [(Sar)~__n__~ο£ΏAzoο£Ώ(Sar)~__n__~], were prepared with the __N__βcarboxyanhydride method. The oligomers were coupled with an equimolar amount of succinyl chloride in the presence of
Rate constants k iso of the thermal cis-trans isomerization of four 4,4'-nitro-aminoazobenzenes with different amino groups have been determined in homogeneous aprotic solvents and polyglykol oligomers, primarily by means of conventional flash photolysis. The rate constants have been correlated with
