3-乙基-5-[2-(3-乙基-2-苯并亚硒唑啉基)亚乙基]罗丹宁(BSeER)发生从苯并亚硒唑啉环向罗丹宁环的弱电荷转移。其表现为:随溶剂极性增加,可见区长波最大吸收峰红移;有非定域化不成对电子特征的顺磁共振信号;X射线光电子能谱得到的电子结合能偏离正常值和因光电子发射振起过程引起的双峰结构。BSeER属于p型杂质电导,电阻率随温度变化,遵守ρ=ρ_0 exp(⊿E/kT)公式。在空气和真空中的ρ和⊿E分别是:ρ100℃(空气)=7.8×10~(10)Ω·cm,⊿E)(空气)=0.45eV;ρ100℃(真空)=1.8×10~(12)Ω·cm,⊿E(真空)=0.93eV。由于弱电荷转移和由分子对形成分子柱,所以ρ很高。
3-Ethyl-5- [2- (3-ethyl-2-benzoselenoxazolinyl) ethylidene] rhodanin (BSeER) Charge transfer. Its performance is as follows: With the increase of solvent polarity, the maximum absorption peak of long wavelength region shows red shift; there is a paramagnetic resonance signal with non-localized unpaired electron characteristics; the electron binding energy obtained by X-ray photoelectron spectroscopy deviates from the normal value, The bimodal structure caused by the launch vibration. BSeER is a p-type impurity conductance, the resistivity changes with temperature, abide by ρ = ρ_0 exp (⊿ E / kT) formula. Ρ and ⊿E in air and in vacuum are respectively: ρ100 ° C (air) = 7.8 × 10-10 Ω · cm, ⊿E) (air) = 0.45eV; ρ100 ° C (vacuum) = 1.8x10 ~ (12) Ω · cm, ⊿E (vacuum) = 0.93eV. Ρ is very high due to weak charge transfer and formation of molecular columns by molecular pairs.
