Their optical and electrochemical properties were measured using UV-Vis and emission spectroscopic techniques as well as cyclic voltammetry (CV). These compounds show deep green color in both solution and solid state, and are highly soluble in dichloromethane and even in nonpolar solvents such as hexane. The shapes of the absorption spectra of 1a\u20131c in the solution and solid state were found to be almost the same, indicating that the long alkyl chains could efficiently prevent intermolecular contact and aggregation. They show a unique charge transfer emission in the near-infrared region, of which the peak wavelengths exhibit strong solvatochromism. The dipole moments of the molecules have been estimated using the Lippert\u2013Mataga equation, and upon excitation, they show larger dipole moment changes than that  of 1,7-diaminoperylene bisimide (2). Moreover, all the dyes exhibit two irreversible  one-electron oxidations and two quasi-reversible one-electron reductions in dichloromethane at modest potentials. Complementary density functional theory calculations performed on these chromophores are reported in order to rationalize their electronic structure and optical properties.<\/jats:p>","DOI":"10.3390\/ma7117548","type":"journal-article","created":{"date-parts":[[2014,11,24]],"date-time":"2014-11-24T11:06:32Z","timestamp":1416827192000},"page":"7548-7565","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["1,7-Bis-(N,N-dialkylamino)perylene Bisimides:  Facile Synthesis and Characterization as  Near-Infrared Fluorescent Dyes"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2193-688X","authenticated-orcid":false,"given":"Kew-Yu","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering, Feng Chia University, Taichung 40724, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Che-Wei","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Feng Chia University, Taichung 40724, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2014,11,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4226","DOI":"10.1039\/c2cc30948c","article-title":"Phosphorescent perylene imides","volume":"48","author":"Ventura","year":"2012","journal-title":"Chem.
