Abstract:Many aggregation‐induced emission (AIE) molecules based on tetraphenylethylene (TPE) structure have been synthesized, but a clear understanding of the photophysical difference between different isomeric pyridyl‐based tetraphenylethylene molecules remains elusive. Herein, we designed a series of isomeric tetraphenylethylene‐pyridines (o‐Py‐TPE, m‐Py‐TPE, p‐Py‐TPE) to investigate the influence of the position of N atoms in the pyridine subunit on the photophysical property of the whole molecule by detailed DFT c… Show more
