Singlet fission (SF), which generates two triplet excitons (T1) from one singlet exciton, has attracted attention in recent years. Recently, we found that the optical properties of 1,3-diphenylisobenzohuran (DPBF), a typical SF molecule, show atmosphere dependence due to T1 quenching. Furthermore, this time, we found the possibility that this atmosphere dependence also depends on the crystal polymorph, and we report it.
