Abstract
Fused ring oligothiophenes and their derivatives as active organic semiconductors are widely used in electronic devices The influence of molecular conjunction length on reorganization energy electronic coupling and charge mobility of two fused ring oligothiophenes are investigated theoretically The charge mobility of 2 5dithiophen2ylthieno 3 2bthiophene T−T2−T with longer molecular conjunction length is 0226 cm2V−1s−1 which is nearly 3 times larger than that of 2 2bithieno3 2bthiophene T2−T2 as 0085 cm2V−1s−1 The investigation will provide a new perspective to design high mobility organic semiconductors
