We present a theoretical study of soliton formation in long-chain polyenes, including the energy of formation, length, mass, and activation energy for motion. The results provide an explanation of the mobile neutral defect observed in undoped ${(\mathrm{CH})}_{x}$. Since the soliton formation energy is less than that needed to create band excitation, solitons play a fundamental role in the charge-transfer doping mechanism.
The results of an experimental study of the infrared absorption of the ${(\mathrm{CH})}_{x}$ system, lightly doped ( 0.1%) with acceptors and donors, are presented. Additional a...
A study of the electrical conductivity of the halogen doped transpolyacetylene system, (CH)x, is reported. When films of trans- (CH)x are exposed to chlorine, bromine, or iodine...
Ultrafast photoinduced absorption by infrared-active vibrational modes (IRAV) is used to detect charged photoexcitations (polarons) in conjugated luminescent polymers. The exper...
The results of an electron spin resonance (ESR) study of trans-polyacetylene, before and after doping with AsF5, are reported. The undoped polymer exhibits a Lorentzian line (g=...
Electroluminescent (EL) devices are constructed using multilayer organic thin films. The basic structure consists of a hole-transport layer and a luminescent layer. The hole-tra...
