Tuning the color of thermally activated delayed fluorescent properties for spiro-acridine derivatives by structural modification of the acceptor fragment: a DFT study

Abstract

A theoretical investigation on the relationship between the electronic structures and emission properties of thermally activated delayed fluorescent materials based on donor–acceptor type spiro-acridine derivatives has been performed. Efficient color tuning over the whole visible range has been achieved via structural modification of the acceptor fragment.
