Abstract

The invention provides two 1,8-naphthalimide derivatives which respectively have structures of a formula (I) and a formula (II). The 1,8-naphthalimide derivatives which have structures of the formula (I) and the formula (II) respectively contain two and three 1,8-naphthalimide groups. The experiment shows that fluorescence-emission strengths of the derivatives corresponding to the maximum emission wavelength are respectively 1.6 times and 1.9 times as much as the EBNP (4-amino-ethylamino-N-n-butyl-1,8-naphthalimide); and the derivatives have high use rate of fluorogens and have higher fluorescent properties.

Description

technical field

[0001] The invention relates to the field of fluorescent materials, in particular to a 1,8-naphthalimide derivative and a preparation method thereof. Background technique

[0002] 1,8-naphthoimide derivatives are condensation products of 1,8-naphthalene dioic anhydride and primary amines. 1,8-naphthalimide derivatives contain a very planar naphthalene ring structural unit in the molecule. There is a strong electron-donating group at one end, and a strong electron-withdrawing group at the other end, so there is a large "withdrawing-donating electron conjugated system" in its molecular structure, and electrons in such a system are easily attracted When exposed to light, a transition occurs to produce fluorescence.

[0003] At the same time, 1,8-naphthoimide derivatives have a rigid planar structure. First, the rigid planar structure weakens the vibration of molecules, which reduces the interaction between excited state electrons and molecular vibrations, reduc...
