Near-Infrared Absorbing Molecule Based on Triphenylamine Radical Cation with Extended Homoaryl ?-System
نویسندگان
چکیده
Four triphenylamines with extended ?-systems were synthesized. Cyclic voltammetry (CV) measurements showed that they gave radical cations, which are stable in solution. Radical cations obtained upon one electron chemical oxidation strong absorption the near-infrared region. The of naphthalene-substituted derivatives show a maximum wavelength above 1000 nm and classified as NIR-II dyes. Molecular design rules novel absorbing dyes described.

Extended Near-Infrared Resonance Raman Investigations of an Organic Mixed-Valence System: Diazatetracyclodiene Radical Cation
Resonance Raman scattering studies in the extended near-infrared region show that six modes are coupled to the intramolecular charge-transfer transition in the mixed-valence radical cation diazatetracyclodiene. Spectral analysis based on time-dependent scattering theories shows that all six modes make substantial contributions to the vibrational reorganization energy. Measured Raman scattering ...

A series of organosoluble polyamides based on N-phenothiazinylphenyl redox units showing anodically electrochromic characteristics both in the near-infrared (NIR) and visible light regions were prepared from the phosphorylation polyamidation reactions of a newly synthesized diamine monomer, 4,40-diamino-40 0-N-phenothiazinyltriphenylamine, with various dicarboxylic acids. These polymers were re...

Diffuse optical tomography (DOT) is a rapidly growing discipline in recent years. It plays an important role in many fields, such as detecting breast cancer and monitoring the cerebra oxygenation. In this paper, a relatively simple, inexpensive, and conveniently used DOT system is presented in detail, in which only one photomultiplier tube is employed as the detector and an optical multiplexer ...

Organic photodetectors are interesting for low cost, large area optical sensing applications. Combining organic semiconductors with discrete absorption bands outside the visible wavelength range with transparent and conductive electrodes allows for the fabrication of visibly transparent photodetectors. Visibly transparent photodetectors can have far reaching impact in a number of areas includin...
