'Supplementary Information_nat-comm.pdf' In this study, Metal-Organic Frameworks (MOFs) systems have been studied. MOFs have been designed with significant Stokes shift by exploiting fluorescent conjugated acene building blocks arranged in nanocrystals. These nanoemitters are ideal candidates for reabsorption-free photonic applications that require fast timing response. The name of the individual files is a short description of the content that has been explained with details in README.txt. All files are collected in one directory. The file 'README Nature comm.txt' contains short description of the individual files.
