Abstract The recent progress of indole containing opto electronic materials is reviewed , including photochromism ,
electroluminescence and non linear optical materials. The affect of the structural characteristcs and the rich electron cloud
of indole , which is named as benzopyrrole , on the UV vis absorption , emission wavelength , fluorescence intensity ,
quantum yield of the photochromism and electroluminescent materials is summarized. As to the non linear optical
materials containing indole based chromophores , they all show bination of large nonlinearity and relatively good
transparency among the chromophores , providing a new method for defeating the“nonlinear transparency tradeoff”, which
is one of the main problems that restrict the development of the non linear optical materials.
