Abstract Modifying the energy landscape of existing molecular emitters is an attractive challenge with favourable outcomes in chemistry and organic optoelectronic research. It has recently been explored through strong light–matter coupling studies where were placed optical cavity. Nonetheless, a debate revolves around whether observed change material properties represents novel coupled system dynamics or unmasking pre-existing induced by interactions. Here, for first time, we examined effect...
