Aggregation-induced emission, multiple chromisms and self-organization of N-substituted-1,8-naphthalimides
Ge, Shusheng,Li, Baoyan,Meng, Xinlei,Yan, Han,Yang, Mei,Dong, Ben,Lu, Yun
, p. 147 - 153 (2018)
Most aggregation-induced emission (AIE) luminogens possess propeller-like aromatic stator-rotor structures, such as silole, tetraphenylethylene (TPE) and triphenylamine (TPA), to restrict intra-molecular motions (RIM) and avoid aggregation-caused quenchin
Long-lived triplet state charge separation in novel piperidine-bridged donor - Acceptor systems
Van Dijk, Saskia I.,Groen, Cornelis P.,Hartl, Franti?ek,Brouwer, Albert M.,Verhoeven, Jan W.

Two bichromophoric systems are presented that contain an N-alkylnaphthalimide electron acceptor and a 4-methoxyaniline (3a) or an aniline (3b) electron donor, respectively. Upon photoexcitation of 3a in cyclohexane electron transfer occurs in the singlet

The synthesis of N-substituted-1,8-naphthalimides is accelerated in the presence of the room temperature ionic liquid [BMIM][NO3]. Reaction times are reduced from 18 h in volatile organic compounds (VOCs) (PhCH 3, EtOH and THF) to 20 min in the ionic liquid [BMIM][NO 3]. The reaction yields are typically increased to >85% and the products are isolated by ethanol-mediated precipitation direct from the ionic liquid, requiring no further purification. Crown Copyright
A "green" route to perylene dyes: Direct coupling reactions of 1,8-naphthalimide and related compounds under mild conditions using a "new" base complex reagent, t-BuOK/DBN
Sakamoto,Pac
, p. 94 - 98 (2007/10/03)
The direct coupling reactions of 1,8-naphthalimide compounds efficiently occurred at 130 or 170 °C without the intervention of the leuco form dyes in the presence of base complex reagent, t-BuOK/1,5-diazabicyclo[4.3.0]non-5-ene (DBN), to give the corresponding perylene dyes in good yields with >95% purities. A possible mechanistic speculation for these oxidative coupling reactions is briefly discussed.
Stereoselectivity of Radical Additions of N-Haloimides to Cyclic Alkenes
Kirsch, Andre,Luening, Ulrich,Krueger, Oliver
, p. 649 - 656 (2007/10/03)
The addition of N-haloimides (1-5) to alkenes 9 via imidyl radicals 6-8 introduces a halogen atom and an imidyl moiety to vicinal C-atoms of a carbon chain. With cyclic alkenes, the trans/cis-stereoselectivity depends on the nature of the imidyl unit, on the halogen atom, and on the alkene and varied between 58 : 42 and >95 : 5. Temperature dependend studies showed higher trans/cis-selectivities at elevated temperatures, which may be caused by different conformations of the adduct radicals 10-12, each of them exhibiting a different stereoselectivity.
N-SUBSTITUTED ISONAPHTHALIMIDES. FORMATION AND REACTION WITH AMINES
Ganin, E. V.,Makarov, V. F.,Nikitin, V. I.
, p. 2209 - 2215 (2007/10/02)
N-Substituted isonaphthalimides and N-substituted naphthalimides, as considered previously, are formed in the reaction of 1,8-naphthaloyl chloride with primary amines.The reaction of N-substituted isonaphthalimides with sterically unhindered amines leads to the N,N'-substituted diamides of 1,8-naphthalenedicarboxylic acid.In the case of sterically hindered amines it results in isomerization to the N-substituted naphthalimides.The thermolysis of the N,N'-substituted diamides of 1,8-naphthalenedicarboxylic acid leads to amines and N-substituted naphthalimides.
