Metallo‐Supramolecular Gels that are Photocleavable with Visible and Near‐Infrared Irradiation
نویسندگان
چکیده
A photolabile ruthenium-based complex, [Ru(bpy)2 (4AMP)2 ](PF6 )2 , (4AMP=4-(aminomethyl)pyridine) is incorporated into polyurea organo- and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long-term stability in the dark, cleavage of the pyridine-ruthenium bond upon irradiation with visible or near-infrared irradiation (in a two-photon process) leads to rapid de-gelation of the supramolecular gels, thus enabling spatiotemporal micropatterning by photomasking or pulsed NIR-laser irradiation.

Nondestructive Firmness Estimation of Tomato Fruit Using Near-Infrared Spectroscopy
Today, nondestructive methods are widely used to determine the quality of agricultural products. Meanwhile, visible and near-infrared (Vis/NIR) spectroscopy is regarded as one of the most widely used methods in the field of quality assessment of agricultural products. In this study, a system was developed to measure the Vis/NIR spectra of tomato fruit samples in the half-transmittance mode of m...
متن کاملNear infrared light-responsive and injectable supramolecular hydrogels for on-demand drug delivery.
A near infrared (NIR) light-responsive supramolecular hydrogel consisting of α-cyclodextrin and poly(ethylene glycol)-modified dendrimer-encapsulated platinum nanoparticles was developed. Upon NIR irradiation, this hydrogel underwent a photothermo-sensitive degradation to release the entrapped therapeutic agents in an on-demand and dose-tunable fashion.
متن کاملReversible thermo-responsive luminescent metallo-supramolecular triblock copolymers based on platinum(II) terpyridyl chromophores with unusual aggregation behaviour and red-near-infrared (NIR) emission upon heating.
Two platinum(II) terpyridyl-based metallo-supramolecular triblock copolymers, [ClPt(tpy)PEO-PPO-PEO(tpy)PtCl](OTf)(2) (1) and [(Ph-C≡C)Pt(tpy)PEO-PPO-PEO(tpy)Pt(C≡C-Ph)](OTf)(2) (2), have been synthesized and characterized. The two complexes were found to aggregate with PtPt and/or π-π interactions at high temperature, which have not been reported so far, as revealed by UV/Vis absorption, emiss...
متن کاملMetallo-supramolecular cyclic polymers.
Cyclic brush polymers represent an exciting new macromolecular topology. For the first time, this new topology has been combined with metallo-supramolecular interactions to construct novel cyclic brush polymers. Here, ring-expansion metathesis polymerization was used to synthesize a universal cyclic template with a polynorbornene backbone, which was further modified with the metal-chelating syn...

A novel Cu1.8Se/Cu₃Se₂ composite photocatalyst was prepared by the simple precipitation method. This composite possesses a wide photoabsorption until the range of near-infrared light, and exhibits significantly enhanced photocatalytic activity for methyl orange degradation under visible and near-infrared light irradiation compared with bare Cu1.8Se and Cu₃Se₂. The mechanism of this outstanding ...
