Molecules comprised of two or more switches have potential to exist in a variety states, which may only be accessible by “correct” sequence stimuli on account the influence neighboring unit. Here we present straightforward synthesis dyad incorporating photoswitchable units, dihydroazulene (DHA) and spiropyran (SP). The photoswitching properties both chromophores acido-triggered switching SP wer...

The photoisomerization kinetics of aqueous solutions of cefuroxime axetil under irradiation at 254 nm was investigated by HPLC. The overall degradation is the result of a competition between the isomerization of the alkoxyimino group and the photolysis of the beta-lactam ring. Cefuroxime axetil exists as a mixture of two diastereomers which are shown to react at different rates. This is true no...

E n e r g y l a n d s c a pe that governs the chemical reaction of two molecules after the system absorbs one single photon. At the first reaction step t0 the system consists of five molecules strongly interacting with the electromagnetic vacuum. At the second reaction step t1 the system has evolved and one molecule has isomerized. In the strong coupling regime this process continues with more ...
