Key Points

This research aims to explore the emission properties of a small donor-acceptor molecule that breaches Kasha's rule.
Investigation of a small organic molecule with a molecular weight of 260 Da
Analysis of light emissions from two excited states
Examination of photophysical properties and donor-acceptor effects
The molecule emits multicolour and red light due to two distinct excited states
Simultaneous anti-Kasha and donor-acceptor effects enhance emission properties
Unique emissions established for this size of organic molecule

Implication

This report demonstrates red and multicolour emissions in a small organic molecule, suggesting novel photophysical properties.

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...
