  • Descrição: The search for a unique molecular system able to efficiently emit in the total visible range of the electromagnetic spectra, i. e., white light emission (WLE), is a topic of intense research. We here show that aggregates formed by diphenylbenzofulvene (DPBF) derivatives are from two to four orders of magnitude more emissive than their monomers. From a simple strategy, involving structural modification of a DPBF propelled shape core, a close match with the pure white light emission coordinates is obtained with a combination of two derivatives in films, with featured solid‐state emission, without involvement of D−A groups or energy transfer processes. Even though the aggregation‐induced emission phenomena have been described for diphenylbenzofulvene derivatives for about 15 years, their solid‐state emission in films has not been previously studied. Hereby, their solid‐state emission is characterized and the white light emission of a thin film made of mixture of the derivatives DPBFMe and DPMF(Me)2 is deciphered.
