Theoretical Study on Emission Enhancement of Solid Trans-Stilbene in Low Pressure Region
Mechanoresponsive luminescent materials have attracted much attention for their potential applications in mechanical sensors,memory chips,and safety inks,especially those with pressure induced emission enhancement(PIEE)properties.In this work,combina-tion of quantum and molecular mechanics methods was used to theoretically confirm the PIEE of trans-stilbene crystals in the low pres-sure region(<1.0 GPa).The calculation results show that the reduction of the non-radiative transition rate is the most fundamental reason for the emission enhancement.This study solves the problem of solid molecular fluorescence calculation and provides an auxiliary idea for the design of materials with PIEE.
