The authors discuss the synthesis of two carbon cluster-based chelating tridentate ligands, terpyridyl-pyrrolidine-fullerene (C60-tpy) and terpyridyl-pyrrolidine multiwalled carbon nanotube (MWCNT-tpy), by 1,3-dipolar cycloaddition. The two che
The effect of pore size and layer number of metal-porphyrin coordination nanosheets on sensing DNA

Metal-organic framework (MOF) nanosheets are a new type of two-dimensional nanomaterial. Their properties and performances are expected to correlate strongly with the sheet structure, particularly the number of layers (sheet thickness). Yet, synthetically controlling the layer number at the molecular scale is highly difficult. Herein, a facile method is introduced to fabricate substrate-supported MOF nanosheets with precisely controllable layer numbers, using the Langmuir-Blodgett technique. Large-area, porous, and uniform MOF nanosheets, based on 5,10,15,20-tetrakis[4′-(terpyridinyl)phenyl]porphyrin-cobalt(ii) (Co-TTPP) coordination polymer, were constructed and characterized in detail by atomic force microscopy, transmission electron microscopy, energy dispersive spectroscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy, and a photoelectronic conversion technique. As a prototype sensor device, a series of substrate-supported Co-TTPP nanosheets was further investigated for the fluorescence detection of DNA towards rapid clinical diagnosis. The ten-layer Co-TTPP nanosheet exhibits an impressive performance with a very low detection limit of ca. 0.1 nM, outstanding specificity, and multiplexed DNA detection, comparable to some top-notch free-standing nanomaterial sensors. Importantly, our results also revealed the synergistic contributions of suitable pore size and optimal layer number of the Co-TTPP nanosheet for highly efficient DNA detection for the first time.

On the basis of BODIPY platform, a terpyridyl-substituent BODIPY-Copper complex (Cu(II)-BTPY)was rationally designed and synthesized as a redox reaction fluorescent sensor for detecting HNO over reactive oxygen species (ROS)and reactive nitrogen species (
A ternary memory module using low-voltage control over optical properties of metal-polypyridyl monolayers
Kumar, Anup,Chhatwal, Megha,Mondal, Prakash Chandra,Singh, Vikram,Singh, Alok Kumar,Cristaldi, Domenico A.,Gupta, Rinkoo D.,Gulino, Antonino
, p. 3783 - 3785 (2014)
A ternary memory module has been designed as a function of precise voltage command. The monolayer based module displays perpetual stability and non-hysteretic reversibility for multiple scans (102). Ternary-state readout provides a vision to integrate the next generation of "smart electro-optical devices" viable for multi-state memory. This journal is the Partner Organisations 2014.
Free radical oxidation reaction for selectively solvatochromic sensors with dynamic sensing ability
Shen, Fengjuan,Wang, Tao,Yu, Xudong,Li, Yajuan
, p. 1919 - 1922 (2020)
A novel BODIPY (boradiazaindacene) dye denoted as BODIPY-DT containing terpyridine unit has been designed and characterized. The dye is found to be selective and visual solvatochromic sensor toward DMF among test organic solvents. The sensing process displays time-controllable, dynamic signal outputs in the emission colors including red, purple, yellow and even white emission colors. It is presented that selective free radical oxidation reaction happens during the recognition process.

Terpyridinebenzaldehyde isomers: One-pot facile synthesis
Jouaiti, Abdelaziz
supporting information, p. 1547 - 1555 (2021/02/27)
We have explored the use of (diethoxymethyl)benzaldehyde readily available as a starting material allowing us to end up with Terpyridinebenzaldehyde isomers. An environmentally friendly procedure was undertaken for the synthesis of a series of 4, 3 and 2-([2,2′:6′,2″-terpyridin]-4′-yl)benzaldehyde isomers (para, meta and ortho position). These compounds have been synthesized in one-pot conditions using ethanol and aqueous ammonia as solvents, at room temperature. This methodology offers substantial advantages with respect to its simplicity of operation, reaction time, satisfying yield of products and easy work-up procedure under mild reaction conditions. Apart from spectroscopic characterization, the structure of one of the Terpyridinebenzaldehyde derivative is confirmed by single-crystal X-ray diffraction.
