Über die elektrische Leitfähigkeit von Jod- und Brommolekülkomplexen der (1-Aryl-3-isoindolyl-) (1-aryl-3-pseudoisoindolenyliden)-arylmethane und ihre Metallderivate

摘要

It was established that the said substances possess comparatively low specific electrical resistence (compared to similar substances having a tertiary nitrogen atom) which decreases exponentially with increasing temperature. The investigated molecular complexes have the properties of thermistors. On the basis of the experimental data the electron constant „B”, the temperature coefficient „α” and the energy of activation „ΔE” were calculated. The values of the energy of activation are within the so far established limits (from 0 upto 1.5 eV) for complexes with charge transmittance, such as the investigat
