N-phenyl maleimide,1-Phenyl-1H-pyrrole-2,5-dione,N-phenylmaleic imide、Maleimidobenzene is abbreviated NPMI or N-PMI,pale-yellow aciform crystals.The melting point is 88～92℃.NPMI is a kind of heat resisting organic monomer,and can increase material thermostability by raising intemal rotation resistance of macromolecular,using its special molecular struture.

N-苯基马来酰亚胺俗称&单马&，英文名称为；N-phenyl maleimide、1-Phenyl-1H-pyrrole-2，5-dione、N-phenylmaleic imide、Maleimidobenzene，英文缩写NPMI，淡黄色片状晶体，熔点为88～92℃，是近年发展起来的一种耐热有机单体，由于它具有五元环状平面结构，嵌入高分子链中可增加链的内旋阻力，从而提高材料的耐热性。

Absorption spectra indicate that there is little or no interaction between chromphores in the ground state. However, the fluorescence emission of oxadiazole and triphenylamine moieties are almost quenched, which shows that in the excited ground state there exists very effective intramolecular singlet-singlet energy transfer .

研究发现，这些多发色团化合物在基态发色团之间没有作用或作用很小，而其中噁二唑和三苯基胺单元的荧光被严重的猝灭，这说明在激发态下，萘酰亚胺发色团与噁二唑、三苯胺功能团之间发生了分子内单线态—单线态能量转移。
