“…The nitration of this framework led to the early isolation of 1H-naphtho[1,8de]1,2,3-triazine as one of the first 1,2,3-triazines to be prepared. [27,28] In general, these triazines have good water and oxygen stability and are readily derivatized with a range of electrophiles. [29] Although poor solubility is a potential practical pitfall with this type of system, for the derivatives here, even the salts, it is not an issue.…”

By careful choice of reaction conditions 1‐methylnaphtho[1,8‐de]‐1,2,3‐triazine and 1,3‐dimethylnaphtho[1,8‐de]‐1,2,3‐triazinium triflate are readily prepared by the alkylation of 1H‐naphtho[1,8‐de]‐1,2,3‐triazine. The electronic spectra for these bathochromically shifted dyes are reported for a range of solvents as are their vibrational spectra and theoretical structures from density functional theory, B3LYP/6‐311++G**. The 15N substitution into the middle nitrogen atom allows for the identification of strong azine bands in the IR and Raman spectra as well as in the 15N NMR spectrum. X‐ray crystallography is used to characterize the solid‐state structures of two of these new triazine derivatives and these structures are used to benchmark the theoretical and spectroscopic discussions. The corresponding 1,3‐dimethyltriazinium radical is prepared and characterized by cyclic voltammetry, spectroelectrochemistry, and EPR spectroscopy. Unlike the related transient 1,2,4‐triazene radicals, the 1,3‐dimethyl‐1,2,3‐naphthotriazyl radical is markedly more stable.

“…Polycrystalline perpendicularly magnetized films may have, however, symmetric radiation patterns (in the absence of Oersted fields). In addition, STNO can be frequency and phase locked to external oscillatory signals or to other STNO frequencies under certain conditions [9][10][11][12][13][14][15][16][17].…”

Spin torque nano-oscillators (STNO) are nanoscale devices that can convert a direct current into short wavelength spin wave excitations in a ferromagnetic layer. We show that arrays of STNO can be used to create directional spin wave radiation similarly to electromagnetic antennas. Combining STNO excitations with planar spin waves also creates interference patterns. We show that these interference patterns are static and have information on the wavelength and phase of the spin waves emitted from the STNO. We describe a means of actively controlling spin wave radiation patterns with the direct current flowing through STNO, which is useful in on-chip communication and information processing and could be a promising technique for studying short wavelength spin waves in different materials.
