PPS issue 8 is now online; you can read the issue here. The front cover highlights work from Seiji Tobita and co-workers in Japan. Their paper demonstrates that a coumarin analogue 8-methoxy-4-methyl-2H-benzo[g]chromen-2-one (MMBC), is almost non-fluorescent in non-polar media, whereas it exhibits dramatically enhanced fluorescence in polar protic solvents. The team investigate the mechanistic features of the significant solvent effects on the fluorescence properties of MMBC and a related compound using time-resolved fluorescence and photoacoustic measurements and by theoretical calculations.
