“…Additionally, there are a few more studies on biomolecular consequences of attaching azobenzene at peptide or protein side chains. [40][41][42][43] However, these did not investigate in detail the structural changes induced by photoisomerization. Finally, there is quite a body of literature on poly-a-amino acids containing multiple side-chain azobenzene groups, reviewed for example in ref.…”

“…No exemplo abaixo o ligante 1, com oxigênio (caráter eletrostática ou "base dura") complexa seletivamente o íon sódio (ácido duro) e o ligante 2, com enxofre (caráter covalente ou "base mole") complexa seletivamente o íon prata (ácido mole); 3) a formação de ligações de hidrogênio com geometria adequada; um exemplo é o caso de amidas de calixarenos, que variam a seletividade de acordo com o grupo ligado diretamente ao ane; se o C=O se liga ao anel, ocorre a complexação de cátions amônio (LIEN et al, 1996), e, se o grupo N-H se liga ao anel, carboxilatos são complexados (LAZZAROTTO et al, 2001). …”

“…In a particularly elegant example, the size of nanochannels could be modified by irradiating azo ligands that decorate the channel walls (Liu et al, 2004). Azoderivatized gramicidin ion channels represent a unique case where ion transport can be photocontrolled by the optical manipulation of a biomolecule (Lien et al, 1996). In addition to obvious applications in controlled transport, this offers the possibility of studying cells by controlling the timing of ion exchange processes.…”
