具有分子内电荷转移特性的新型萘酰亚胺衍生物合成及发光性能
Synthesis and photochemical properties of two ICT compounds with naphthalimide and diarylamine units
摘要
Abstract
Two new diarylamine-substituted 1, 8-naphthalimidederivatives are synthesized by Cu Ⅰ/18-crown-6/K2CO3 catalystsystem and characterized by Fourier transform infrared (FF-IR), 1H-NMR and elemental analyses. The UV-vis absorption andphotoluminescent (PL)spectra of the systems in n-hexane,tetrahydrofuran (THF), and CH2Cl2 are investigated. Thesenaphthalimide molecules have an absorption band centered atabout 450 nm, which is assigned to an intramolecular charge-transfer (ICT)transition, and they emit light at 492, 501 nm in anonpolar solvent such as n-hexane, and at 600,620 nm in a polarsolvent such as CH2Cl2. From the Lippert-Mataga equation, thedifference of the dipole moment between the excited state and theground state is estimated to be 9.2 and 9.8 D for 4-(diphenylamine )-N-( 2-methoxyphenyl )-1, 8-naphthalimide( DMN-1 ) and 4-( 2-naphthylphenylamine )-N-( 2-methoxyphenyl) -1, 8-naphthalimide (DMN-2), respectively. Thislarge change in the dipole moment upon excitation is typical forphotoinduced ICT processes.关键词
