The article focuses on the study by Chihaya Adachi and his Kyushu University in Japan colleagues on forcing orbitals in fluorescent molecules to reside on a different part of the molecule instead of spreading. Adachi and his team embedded each carbazolyl dicyanobenzenes (CDCB) in an organic host film to make their prototype organic light-emitting diodes (OLED). Achieving consistent efficiency and tailoring the fluorescence wavelengths are among the challenges they met in the study.
