Multi-colour and red emissions from a small donor-acceptor molecule by breaching Kasha's rule
Abstract
Reported herein is a small (MW 260 Da) organic molecule that emits multicolour and red lights, capitalising simultaneous anti-Kasha and donor-acceptor effects. The molecule emits from two excited states, namely S1 and S3. Introduction of donor-acceptor substituents resulted in the large Stokes shifts (>5000 cm -1 ) with negligible spectral overlap.
