This paper describes a series of four ortho-nitrobenzyl substituted bis(norbornene) crosslinkers that are suitable for the preparation of photoresponsive organogels and hydrogels through ring-opening metathesis polymerization As measured by several techniques-visual inspections, rheol., and release of network-bound polymers-organogels prepared using these four crosslinkers varied in their sensitivity to UV irradiation by about two orders of magnitude. The reactivity of the gels shows qual. correlation with the stability of the intermediate benzylic radicals. Gels with larger crosslink densities required longer UV irradiation time to dissolve than gels with smaller crosslink densities. Together, these results demonstrate how rational changes to the structures of crosslinkers and gels can tune photosensitivity. Finally, we show a proof-of-concept photochem. release experiment of a phys. entrapped fluorescent polymer from a photolabile ROMP hydrogel. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Application of 60463-12-9).
3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Application of 60463-12-9
