## TL;DR

This paper explores how LMCT chromophores in donor-acceptor dyads can efficiently form triplet states through an electron transfer pathway.

## Contribution

The study introduces a cascade mechanism for generating triplets from 2LMCT states using earth-abundant materials.

## Key findings

- LMCT chromophores enable efficient triplet state formation via electron transfer.
- The cascade mechanism enhances the generation of triplets from 2LMCT states.

## Abstract

Earth-abundant ligand-to-metal charge transfer (LMCT) chromophores
in donor–acceptor dyads unlock an electron
transfer pathway for efficient triplet state formation.
