Spectral and photochromic properties of spironaphthooxazines (SNOs) with piperidine and morpholine substituents have been studied at different temperatures in various solvents. It has been recognized that introduction of these substituents in naphthooxazine fragment leads to fluorescence of the initial form of SNO mols. at low temperatures, which disappears with temperature rise. The dependences of the photoinduced form of spectral characteristics on temperature and concentration make it possible to assume the aggregation of the mols. of photoinduced form in non-polar solvents. It is proposed that the colored form of substituted SNOs has a bipolar structure with a pos. charge on piperidine or morpholine nitrogen atom contrary to the quinonoic form of unsubstituted SNO. In the experiment, the researchers used many compounds, for example, 1,3,3-Trimethyl-6′-(piperidin-1-yl)spiro[indoline-2,3′-naphtho[2,1-b][1,4]oxazine] (cas: 114747-45-4Related Products of 114747-45-4).
1,3,3-Trimethyl-6′-(piperidin-1-yl)spiro[indoline-2,3′-naphtho[2,1-b][1,4]oxazine] (cas: 114747-45-4) belongs to piperidine derivatives. Piperidine is a saturated organic heteromonocyclic parent, an azacycloalkane, a secondary amine and a member of piperidines. Fluorinated piperidines are also the subject of continued interest in medicinal chemistry, for example in the synthesis of selective dipeptidyl peptidase II (DPP II) inhibitors. Piperidine derivatives are also used in solid-phase peptide synthesis (SPPS) and many degradation reactions.Related Products of 114747-45-4
