Electron conductance of N , N ′ -bis-(1-naphthl)-diphenyl- 1 , 1 ′ -biphenyl- 4 , 4 ′ -diamine at low temperatures

The electron conductance of N , N ′ -bis-(1-naphthl)-diphenyl- 1 , 1 ′ -biphenyl- 4 , 4 ′ -diamine was found to increase with decreasing temperature experimentally. This phenomenon is quite abnormal since for most organic materials the conductance increases with increasing temperature. A probable ex...

Description
Summary:The electron conductance of N , N ′ -bis-(1-naphthl)-diphenyl- 1 , 1 ′ -biphenyl- 4 , 4 ′ -diamine was found to increase with decreasing temperature experimentally. This phenomenon is quite abnormal since for most organic materials the conductance increases with increasing temperature. A probable explanation was given according to a previous work about soliton diffusion in polyacetylene within the framework of SSH model.
